Bipolar Couple

I know most people will tell me this is a bad idea and that it isn't going to work. I have had one of the therapist tell me this. My girlfriend and I(yes, were lesbians, too) are both bipolar and have been together for almost a year now. it was been rather rocky, too. here recently my girlfriend has been very bad depressed. she has cut and contemplated suicide. I have been doing my best to stay strong for her but its hard with her consist negativity. I know its her depression talking but its so hard not to take it personally. I need some help and advice to get through this, to allow her to get through this. I am taking with my therapist about how to be better there for her. i am really trying my best. i know I have done really bad with this at times. I have let my own feeling get in the way. i am trying to keep them in and to myself more. i am even coming here to get help. today is a very bad day.

My ex who won't get over my(my kid father) texted me this morning and she doesn't like him and thinks he's trying to minipulate me to get back with him. She says ill do it out of guilt. Her depression doesn't help because she tends to get very paranoid. Especially when it comes to him. Can she really be depressed forever? I miss her so much.
