Ah--well, how long has it lasted, and how big were the gaps between his coming to you?
What exactly is he doing? Certain behaviors are extremely indicative of specific problems, but just "depressed" doesn't suggest much other than referring him to a therapist.
This one, too.
Sorry, I wasn't very specific! The last he talked to me, about how he felt, wasn't even a couple hours back, and the first time we talked about that was a few days ago. One morning I woke up, and checked my skype to find a "See you in hell" message in my most recent contacts, which just left me bewildered. He wasn't online at the time, so I couldn't ask him what was up. I forgot about it, as he hadn't logged on until later that day. A day goes by, before I finally ask him why he sent me his bizarre message.
At first he refused to tell me, but I was persistent; he told me he had been contemplating suicide that night. Worried, I asked what made him think about doing such a thing.
He starts to tell me about how he was just dealing with a relationship, and assures me that he will be fine.
A week goes by, and we stay in contact, talking like normal. He wasn't necessarily happy, but fine as far as I could tell. Then, one morning, before he goes to work, we start talking again. He was acting a little upset, so I asked why. He told me, "Because I'm a suicidal wreck that gets upset over friendships going awry and me still holding onto them because I care about them. But I always end up screwing it up. I'm a loser, and always will be."
After that, I comforted him, and calmed him down.
The next time we talk, three days later, today, about him having lost another friend, that told him he was acting like a stalker, and annoying. I can't really explain how he acted, but I have the logs of when we talked that day. (Yes, it was on Skype.) Since I'm not a therapist, I just did what I could. (I'm also sleep-deprived right now, so excuse me if this all looks rushed.)
[2/21/2013 8:46:49 PM] Tsukasa Hiiragi: You need to calm down, Zachary..
[2/21/2013 8:49:20 PM] Zachary Zakrzewski: Calm? No. I'm tired of trying to calm, when everything, everyone, anyhow they can, abandons me, grows tired of me, leaves me to be alone, I'm the worst of the worst, terrible and cursed to live this life a broken dream.
[2/21/2013 8:50:31 PM] Zachary Zakrzewski: I don't deserve love, I don't deserve happiness.
[2/21/2013 8:50:47 PM] Zachary Zakrzewski: So have others deemed for me, so it shall be.
[2/21/2013 9:01:57 PM] Zachary Zakrzewski: ...My thoughts are spat upon, my dreams dashed, my optimism trampled.
[2/21/2013 9:02:17 PM] Zachary Zakrzewski: My insight insulted, my generosity mocked.
[2/21/2013 9:02:41 PM] Zachary Zakrzewski: my caringness treated as being a stalker.
[2/21/2013 9:04:56 PM] Tsukasa Hiiragi: Zachary, you and I have known each other for a while..
[2/21/2013 9:06:05 PM] Tsukasa Hiiragi: And, I want to tell you something.
[2/21/2013 9:08:04 PM] Tsukasa Hiiragi: ..
[2/21/2013 9:08:06 PM] Tsukasa Hiiragi: If you'll listen.
[2/21/2013 9:08:41 PM] Zachary Zakrzewski: What is it?
[2/21/2013 9:14:01 PM] Tsukasa Hiiragi: Do you remember what I told you, a little while ago?
[2/21/2013 9:14:06 PM] Tsukasa Hiiragi: Maybe a few days?
[2/21/2013 9:14:40 PM] Zachary Zakrzewski: ...What was it, exactly?
[2/21/2013 9:15:20 PM] Tsukasa Hiiragi: I reminded you of just how much of a likeable person you are, and how many other people there are that would be happy to be your friend.
[2/21/2013 9:16:21 PM] Zachary Zakrzewski: I don't believe that.
[2/21/2013 9:16:28 PM] Zachary Zakrzewski: Ask anyone who is my friend. Ask anyone.
[2/21/2013 9:16:39 PM] Zachary Zakrzewski: ..Ask people on the game you were on.
[2/21/2013 9:16:48 PM] Zachary Zakrzewski: What they think of Zak attacks.
[2/21/2013 9:16:53 PM] Zachary Zakrzewski: ...They'll tell you.
[2/21/2013 9:16:54 PM] Tsukasa Hiiragi: I AM your damn friend, Zachary. And I don't believe a word of what you said.
[2/21/2013 9:17:10 PM] Tsukasa Hiiragi: This fictional thing you think you are, it's not right.
[2/21/2013 9:17:18 PM] Zachary Zakrzewski: They'll tell you why I'm worthless.
[2/21/2013 9:18:20 PM] Tsukasa Hiiragi: But you're NOT worthless, Zachary. I've known you long enough, to remember back when you were such a happy, spirited, and cheerful guy.
[2/21/2013 9:18:34 PM] Tsukasa Hiiragi: So you lost a couple friends?
[2/21/2013 9:18:36 PM] Tsukasa Hiiragi: Get more. You can.
[2/21/2013 9:18:45 PM] Tsukasa Hiiragi: You have me, and some others.
[2/21/2013 9:18:49 PM] Tsukasa Hiiragi: It's not the end of the world.
[2/21/2013 9:19:12 PM] Tsukasa Hiiragi: One of the reasons I liked you, is because of just how cheerful you seemed.
[2/21/2013 9:19:43 PM] Tsukasa Hiiragi: And I still do.
[2/21/2013 9:20:02 PM] Tsukasa Hiiragi: Why are you telling yourself these dumb things?
[2/21/2013 9:20:17 PM] Zachary Zakrzewski: Because thats what these people treat me like!
[2/21/2013 9:20:22 PM] Zachary Zakrzewski: Thats what I am to them.
[2/21/2013 9:20:27 PM] Zachary Zakrzewski: ...And therefore, it must be true.
[2/21/2013 9:20:57 PM] Tsukasa Hiiragi: You shouldn't believe what you're told, about yourself.
[2/21/2013 9:21:09 PM] Tsukasa Hiiragi: Nobody knows you, better than you. Think for a second.
[2/21/2013 9:21:15 PM] Tsukasa Hiiragi: Are you really annoying?
[2/21/2013 9:21:27 PM] Tsukasa Hiiragi: Are you a stalker?
[2/21/2013 9:21:30 PM] Tsukasa Hiiragi: Do you stalk people?
[2/21/2013 9:21:55 PM] Tsukasa Hiiragi: I don't think so.
[2/21/2013 9:22:32 PM] Zachary Zakrzewski: I don't know.
[2/21/2013 9:22:36 PM] Zachary Zakrzewski: Not anymore.
[2/21/2013 9:22:54 PM] Tsukasa Hiiragi: Well, let's see, in all the time you've known me, I've summed together that, A
[2/21/2013 9:22:56 PM] Tsukasa Hiiragi: You're not a stalker.
[2/21/2013 9:23:01 PM] Tsukasa Hiiragi: B, you're not annoying.
[2/21/2013 9:23:17 PM] Tsukasa Hiiragi: C, you're a nice guy.
[2/21/2013 9:23:44 PM] Tsukasa Hiiragi: And D, you're fun to be around in general.
[2/21/2013 9:24:22 PM] Tsukasa Hiiragi: Stop being so hopeless, -everyone- deserves love, and happiness.
[2/21/2013 9:24:34 PM] Tsukasa Hiiragi: Even your enemies.
[2/21/2013 9:24:56 PM] Tsukasa Hiiragi: Stop holding a grudge against yourself for no reason, Zachary.
[2/21/2013 9:24:59 PM] Tsukasa Hiiragi: Cheer up.
[2/21/2013 9:25:23 PM] Zachary Zakrzewski: I just feel like a failure, is all.
[2/21/2013 9:26:04 PM] Tsukasa Hiiragi: We all have our hardships, Zachary. Sometimes, we all feel low.
[2/21/2013 9:26:16 PM] Tsukasa Hiiragi: But, you know what I do when I'm starting to feel miserable?
[2/21/2013 9:26:17 PM] Tsukasa Hiiragi: And wretched?
[2/21/2013 9:26:27 PM] Tsukasa Hiiragi: And that there's nothing good about my future?
[2/21/2013 9:26:35 PM] Tsukasa Hiiragi: I go to God.
[2/21/2013 9:26:46 PM] Tsukasa Hiiragi: I think to myself, about things.
[2/21/2013 9:27:37 PM] Tsukasa Hiiragi: I thank God for all the blessings I currently have.
[2/21/2013 9:27:40 PM] Tsukasa Hiiragi: And I move on.
[2/21/2013 9:30:18 PM] Tsukasa Hiiragi: I talk with friends, and think about the good in life.
[2/21/2013 9:31:58 PM] Tsukasa Hiiragi: Just aknowledge the fact that you're not a failure, Zachary.
[2/21/2013 9:32:13 PM] Tsukasa Hiiragi: A lot of people probably care about you.
[2/21/2013 9:32:16 PM] Tsukasa Hiiragi: A lot.
This is the conversation we had just a few hours ago. Excuse my laziness in not summarizing everything. I'm just recovering from late-night studying and might not be all there. I also hope I'm not over-reacting, either.
