It sounds like she's trying to control and manage your illness because she is afraid of it. Maybe a support group for friends and family along with support for bipolars might help. I am fortunate to have married another manic depressive and we completely understand the other without judgement or pushing. We have had many difficulties when one is up the other down and lots of excitement when we're both manic and alas, yes...many tears. My other family members don't care to understand and my mother who was blissfully ignorant of bipolar treated me like your gf treats you. She would try to force me to walk four miles a day on days when I couldn't get out of bed. I tried so hard to please her but when I became manic she dumped me off at the ER and told the nurses station that she was done with me. Then she left. Most people don't get it. My husband can see my illness with more clarity than I see it myself and vice versa so we make a good team. We intuit the patterns of the other and try to help them.
