I recently moved back into my parent's rather large house. They told me that some relatives had moved in recently as well. Apparently an entire nuclear family. Didn't care about that with the current state of my income, and moved in.
Now, everything was all fine and dandy for a month, then I actually left my room and conversed with them. Turns out my cousin (isn't my first one, but I don't really know where she is on my family tree) is one incredibly depressed girl of 18 years old. It doesn't help that she confesses she has a crush on me. I don't know how, considering she's had maybe eight glimpses of me when I had to leave my room for food, work, and school, and talked for about 20 minutes total. Anyways, she goes on to tell me a whole bunch of stuff about her best childhood friend telling her that she "doesn't need her anymore", her ex-boyfriend breaking up with her, and how I'll never return her feeling due to being related. Being a fairly care-free dude for the most of my life, I was only able to give a sorry half-assed talk. Her self esteem is quite low, she's ridiculously emotional and cries a lot, and she fears having independence for some reason that I'm not able to understand. I tried to get her to elaborate more on that, but it didn't get anywhere.
Telling her parents does not seem to be a very good option, as her parents read emotions like bricks, and they're likely to be more pissed at her whining than anything else.
She doesn't have insurance, and money is an issue, so going to a doc for antidepressants isn't a choice I can pursue in the short-term.
I'm a 19 year-old guy that doesn't know how to deal with this.
