<human>: Me (16m) and my girlfriend (16f) have been dating for about 6 months. We dated for a year previously, then broke up because things weren't working out. (Jealousy, insecurities, fell for another guy.) So, after a couple months we ended up getting back together and trying things again. Things went smoothly for a while, however, things have been rough lately. I'll just list out my concerns and problems with the relationship and hopefully you guys can tell me what's what. 

1. She is extremely emotional. She has anxiety and depression issues and often gets very very upset out of nowhere. I want to help her and support her but this happens every couple of days and she's so very difficult to help when she's upset. She says that she feels like no one cares about her and that she's not beautiful and she's so tired of being so sad all the time. I do my best to console her by telling her she's beautiful and that lots of people care about her and that I want her to know she's an amazing person. Sometimes it helps for a bit but it always happens again a day or two after. She thinks I haven't done enough to help her and that I should stay up and talk to her. Stuff like that. I really feel like she expects me to be her therapist and try to help her with an issue that needs professional help. Recently my patience has run dry and I get extremely annoyed and frustrated when she has an emotional issue, which she has faulted me on saying that I'm not empathizing with her and that I'm not willing to help her. She also sometimes uses this as an excuse for randomly exploding at me or being irrational. 

2. She has a tendency to overreact to small things. Like when I disagree with her on something she suddenly gets really rude and snotty and raises her voice. 

3. I'm always the bad guy. Always. No matter what we disagree about, and no matter how much I want to be able to tell her I think she's being irrational, I end up surrendering and telling her it won't happen again and that I'll get better. 

I'll give more updates and supply info later. Thanks!
