Patient discussion about force

Q. How to get a bipolar person to get treatment, if refuses to carry this condition? My girlfriend’s mom told me once by phone that my girlfriend was bipolar. I started doing a little research and learned it is difficult to live with this sickness. I don't want to brake up but my safety is fading out now

A. Unless you know for definite that your gf has actually been properly diagnosed for this disorder, you can't tell her to get treatment for a disorder that her mum thinks she may supposedly have. I think you need to have a big long chat with your girlfriend about this and show her your encouragement and support, rather than fear about your safety. She needs someone like you to understand what it is like, and it seems that her bipolar is not an extreme case, otherwise you would have known right away with her behavior. It's caused my having major highs and lows, and if she has been properly diagnosed, encourage her to get the treatment as you care for her and want her to get better!
