I know this probably isn't the right community, but...

I'm likely to lose another friend to suicide in the next few weeks, and there's nothing I can do. He's the last close friend I have left, as the other two already chose suicide earlier this year, one a few weeks ago. I'm honestly fucking miserable right now knowing I'll be alone once again soon enough. I can't make any more friends as my work hours are irregular and make socialising virtually impossible, and as a person, I'm too 'quirky' for most people to like, hence the lack of friends. I think I've turned to nihilism or outright misanthropy in the last year over both the loss of my friends, and the lack of fucks given by wider society about how I feel. On top of all this, I'm overworked, physically exhausted all the time, under appreciated and really quite lonely.

What the hell have I done to deserve my lot?
