I don’t even know where to start. I don’t know what I expect from venting but I need someone to talk to who is out of the situation for an unbiased perspective.
My girlfriend and I have been together for roughly 3 months. I do feel like I have fallen for her ( I know it’s soon, but can’t help it)... we have already had so many good times, good moments and some bad ones. I have depression and anxiety and ADHD and she has Bipolar 2 and ptsd and anxiety. Right now she is un-medicated. And it has been pretty manageable but this last week has been a total mess. I feel drained and like my cup is empty. I feel like I can’t say or do anything right. I respond nicely and try to be caring and listen.. I respond by saying how I feel to give her perspective about where I’m coming from.. I have also responded in not so great ways as well.. I am human.. but I just don’t know. She threatens to leave almost every time she’s upset.. I tell her how I feel and she thinks I’m attacking her and thinks I’m telling her she’s a monster and/or that shes a bad person.. she threatens to end her life and sometimes says that I’m pushing her to that.. she says that she would be better off alone or dead and it doesn’t matter how I try to comfort her it is still the wrong thing.. I say how I feel and it is wrong.. I say nothing and it’s wrong.. everything is just wrong and everything is my fault..
Inside I feel like I have handled things well most of the time and that I have tried to be supportive but I’m at my wits end. A big part of me thinks that all she needs is someone who will be there for her through everything but I can only do so much and I can’t care for my own mental health and hers. It is too much.. I just don’t know where to go from here..

Any advice or thoughts or insight?
