Is OTHER wrong in the post ? POST : I'm a 16M and my girlfriend is a 17F. This is my first legit relationship. 

So basically the deal is I'm sick of my girlfriend not taking care of her mental Illness. It seems like every other day there is some kind of new problem, or she's all of a sudden got an urge to cut, or she just feels bad for no reason. I understand, because I have my own Medically diagnosed Mental health issues. What I don't understand is why she refused to get treatment or any kind of help at all. She was on Medicine for a while but she quit because it was 1. Giving her tremors and 2. She didn't like how it made her feel. Again that's understandable but she hasn't seemed to do anything to supplement it and honestly I can not be her therapist. It's hard enough for me to get through my daily day without trying to shoulder her along with me. I don't want to break up because I'm afraid she's going to hurt herself and because I geniuenly want her to get help. 

She texted me about a half hour ago saying she had the urge to cut. I of course told her not to. She then said it's been going on for too weeks, which annoyed me because she's been saying everything's been fine. So I said she should speak with her therapist, and she said "well I can't do that right now can I?". I said I was here for her in the interim and she said " but not here" as in not at her house. I planned on staying home and I have been sick. Now she has the right to be a little mad cause I went out with my friend last night, so I'm obviously not sick enough to be bed ridden. I tell her I'm sick and say if she needs me to I will come over. She then just starts saying things like don't worry about it and no it's ok, and I reiterate that I'm there for her. Same responses. She invited me over earlier and I said no because her mom nor little sister was home and it makes me uncomfortable going behind her parents back like that. 

I feel guilty because I don't know what more I can do. Even when I've gone to comfort her it doesn't feel like I do much and she's always sad once I'm gone. It's really draining me
