I am 25 and my girlfriend is 30. I just graduated college and my parents agreed to let us stay at their house for the summer while we get on our feet. She has had a long history of mental problems. She grew up with an abusive, neglectful mother who she detests and in her past, she has talked about suicide and attempted suicide before she met me. She also has a history of self harm with cutting scars on her arms. She has had a problem abusing pills in the past and to this day, she takes more than the recommended dose of dipenhydramine on a regular basis. She has been to numerous professionals and recently she was diagnosed with Bipolar II disorder and she is on Abilify and Celexa but is pretty selective about taking them. She also has a history of an eating disorder and whenever my parents talk about losing weight or being healthy, it triggers her eating disorder and she stops eating. She does not eat around my parents and believes that they hate her or dislike her and that is simply not true. She has very strong negative emotional reactions to neutral or even mildly negative situations and she can go from being in a baseline mood to very depressed and self destructive quickly. Sometimes I have had to physically restrain her and prevent her from cutting herself or hitting herself because she can hit herself with her hand or with her phone. She always talks about her being a bad person but I know she is not. She is very self defeating and has a very low self esteem. This has not so much been a problem in the past but lately, she is quick to get angry or to lash out over very small situations. For example: Her laptop was not working properly and she gets very angry and talks about smashing it with a hammer. I was sitting at my desk and everything was seemingly fine when she all of the sudden, started sighing and I asked what was wrong and she said nothing, Then she proceeds to say that she needs her space and leaves the room and when I press her on it, she just tells me to leave her alone. I dont see any malicious behavior here but I see pain coming from her because I know she has a good heart. She can be pretty resistant on getting help which is frustrating, So I want to help her but I am not sure exactly how to help.
