Me and my girlfriend have been together for about a little more than a year now. This is my first serious relationship and she's had a couple casual ones before this. From the start I've know she's had bipolar but had she usually has it controlled with antipsychotics. Though she sometimes just doesn't take them because they require her to eat 300 calories and she's a picky eater with severe depression. This infuriates me because after 4-5 days off of them she starts acting rude, manipulative and annoyed at my existence. I've had multiple conversations with her saying I understand she has her issues but I won't tolerate her stressing me out with constant disrespect and having to walk on eggshells because of her not wanting to eat. Last week after a big fight because I told her she was acting crazy and impossible to be around then she admitted she hadn't been taking her meds while we were home from college for break because her parents didn't have any food she liked got her to set up an emergency meeting with her psychiatrist to get swapped to an antipsychotic that doesn't require food. Tonight was a breaking point for me where | just don't think I can or want to handle this situation anymore. After I got off work she calls asking to take a bath at my house because her parents have a broken tub but I needed to do some maintained on my car so I tell her no. She proceeds to give me an ultimatum. Either she comes to my house or walks around at late at night knowing I hate her doing this. I begrudgingly let her in my house and start asking her why she said that and I had to explain to her why setting the situation up like this was wrong and hurtful. As I come to realize how annoyed I am from her doing this and her giving me a half apology I tell her I'm taking her back to her house. She gets upset and refuses to let me drive her home because of how depressed her house makes her and says she doesn't deserve to be treated like I don't care about her because she isn't doing well mentally right now (the first she tells me about this even since the last big fight where I agreed to not assume her mental state). She then runs off into the night telling me to leave her alone. I get a call 15 minutes later with her balling saying to tell her family she loved them. I then call her mother and tell her what's the matter and her uncle starts driving around trying to find her. During this she starts texting me saying she isn't doing well mentally and I should know to not take her hurtful remarks seriously blaming me for the entire situation. I defuse get her to stop acting out and take her to my house where I let her bathe and play video games while I work on my car. I'm honesty done and know for a fact I'm not emotionally mature enough to handle this woman anymore. I love her so much but don't have enough people skills nor patience to deal with her outbursts. Most of the time we are fine and the relationship is great but when she slips up on her meds I'm not able to trust her for weeks and I feel like this is a cycle that will continue until I just end things. I I’m planning to do so now but don’t know a way to do this without her trying to take her own life as she centers her life around me. How should I handle this?
TLDR: my girlfriend is disrespectful and unbearable off her meds and is too depressed to be on them consiently
