AITA for breaking up with my girlfriend because of her mental health?

I(16) was dating this girl (16) for a few months. We met at an event and we texted a lot until we met again in person. She was great and our relationship was too, exept for one thing: She had pretty big mental health issues. I do too and I get it so I didn't care much about it at first until it started really affecting me.

She saw people that weren't there and heard voices telling her hateful stuff (one time they even told her that her friend wanted her dead) and I felt helpless as I didn't know what to do. She didn't want to get therapy which I understand but I was also at a bad place and it really made everything even harder. Another thing was that everytime I said told her anything that bothered me she'd feel really bad and in the end I'd be the one comforting her (I know that she didn't mean to disregard my feelings she was just pretty traumatised but it still hurt) I really loved her but I was hurting really bad and couldn't also keep her alive but I feel really bad. I know that I really hurt her and she really suffered because of me so I am wondering if I should be feeling bad or not.
