My boyfriend is worried that he might be bipolar, but is too scared to seek professional help. how can i best help him?

Bipolar: You can best help by seeking professional help.

Gently: encourage him to be evaluated. If he is bipolar, then he really does need the professional help that he is avoiding.

He may be bipolar: or he may not be. Best way to find out is to see a mental health professional and get a second opinion if told he is bipolar. That's a very popular diagnosis today and can be overused. Go with him to the doc for support. Peace and good health.

He has to want it: Your boyfriend has to want therapy and medication, and all you can really do is encourage him to seek both and engage deeply and meaningfully in the therapeutic process. You simply cannot do it for him, much as you'd like to. You can either be his girlfriend or his therapist. You cannot be both, and even though you want to see him get better, trying to be both simply will not work.

Support & encourage: him to speak to a professional. Bipolar disorder is a serious illness that can have devastating consequences if left untreated. There remains a lot of stigma around this illness, which makes seeking help difficult for some people. Be supportive and encouraging, offer to go with him (if that helps) and assure him that you care about him regardless of whether he has bipolar or not.
