I am open on FB about my disbility from chronic migraine, and occassionally share links to mental health things. I am not ready to come forward publicly as bipolar, however. I think that my kids would end up with lots of comments they don't need to deal with. Also worry my ex might get custody of my daughter. Response to my posts is usually low, though a coup,e people always say something supportive. I do think that most people just don't know what to say ... I find myself not commenting on things I just am not familiar with. Do it for yourself, and you will gather a following slowly.
