Around a year ago I met a girl on Tinder and we started talking; she shared a lot about herself and her personal life in the month I knew her for (the fact that she was a trans woman and polyamorous, that she used to self harm etc); she seemed to be using me as her personal therapist- I kept telling her to see someone about the issues she was having but she said she couldn’t trust therapists with her problems. 

One day she was telling me about how her ex girlfriend was messaging her again and she decided (for whatever reason) to send me a picture one of her scars that she had done in ‘tribute’ to this person after they broke up. Bear in mind that while the actual scar had healed, she decided to send me a picture of it that she had taken while it was still fresh (so there was a lot of blood).

I struggle with my own mental health at times so seeing that really wasn’t a good thing for me; I made the decision a few days later to block her with an explanation of why- the fact that seeing that picture affected my mental health negatively and that I couldn’t be her personal therapist and that I need to think about myself and put my health first.

TLDR; I blocked a person for dumping all of her personal feelings on me, all while refusing to get actual help from a trained therapist and sending me pictures of triggering material. AITA for doing this?
