What I'm about to say is going to sound harsh, and probably pretty dickish. Nevertheless, I think ya need to consider that it is pretty frustrating to be on the other side of your fence. Especially if he isn't a very emotional or "people person" kinda guy to begin with.

Like the person you're replying to, being around a person who's constantly negative (whether they mean to be or not) can really "drag you down".

Most of us like to imagine we'd be a saint for our friends and loved ones and offer a crying shoulder every time they asked for it. And most of us will gladly offer a sympathetic ear or our shoulders to lean on - for the first dozen times or so. If it becomes something that happens all the time, though, a person's sympathy may begin to wear thin.

It's something almost all of us have experienced in one form or another. Who hasn't gotten annoyed at that one friend who's constantly asking for your help at inconvenient times? You may have lent them a hand with a smile on your face anyway, because you knew it was the right thing to do, but you did feel slightly annoyed. Now imagine if that happened to you every other day, and the person is highly emotional about it ...

If you're struggling with mental health issues, then it isn't your fault that this is happening. And your BF could definitely afford to be nicer to you (turning his xbox up when you're crying is just ... ugh). That said, everybody has a limit, no matter how nice they are or started off as. It isn't your fault if your condition pushes those limits. But -assuming you want this relationship to last- you should have an interest in making sure that it doesn't.
