I am only glad to be of help! c:
As for particular things stressing me, everything. I can't order my thoughts because I am overwhelmed by them. I've also been put down HARD by pretty much everybody and it makes me think my skills and even who I am is worthless. It's the constant rejection after working so hard to avoid that. I get huge anxiety when even thinking about my problems. I try to think of solutions instead; it is massively hard to even think of solutions, much less to put them into practice, because my brain keeps switching to the negative. I can't even talk or think about it without my stomach acting up badly. Mostly I have to distract myself from problems to get through the day and get as much done as I can manage. I feel pathetic.
This sounds A LOT like you're suffering from severe stress. Like, really totally a lot. That's pretty much exactly how i felt when my stress was at its worst, all down to my stomach acting up as well. You sound a lot like a me who has had it much worse, and i'm terribly sorry to hear that. Please, if you haven't already, tell your therapist about this, because such levels of stress are serious, and sound like a very likely cause of depression to me*. I reserve the right to be wrong, but quite honestly, i think that this stress and possibly mindset is wreaking havoc in your system.
I know it's extremely difficult to convince oneself otherwise, but you're not worthless, and neither are your skills, creations or anything otherwise made or done by you. Hell, even your poop is good fertilizer, so that's not worthless either. Your breath? Rich in CO
2, which plants will love you for. But you know what's most important? Not the opinions of others. I KNOW it hurts to be put down, it hurts me to an almost pathological degree, but one the most important parts of being alive is to at least be okay with yourself and what you do. Getting put down by others hurts, but putting yourself down is a vicious circle (but please, don't put yourself down over putting yourself down). A lot of people struggle with this (me included), but remember, you're the one who you can be entirely sure that you have to live with for the rest of your long life. Don't be afraid to think "I am awesome and this is awesome", because what you think is not of anyone elses concern, and for the most part, it's a lot more true than you think. Likewise should the thoughts of others not concern you overly much either, at least not beyond curiosity, because that's a source of stress as well.
It's awesome to hear that you're getting better, depression is a really bad thing that nobody should have to deal with. Keep on trucking, mate!

i seriously hope my ramblings aren't making things worse
