We here DO understand! No, you are not alone. You don't have to tell people you are bipolar, so maybe stop doing that or be very cautious about who you do tell. For some people, family is the worst. You can get understanding HERE! Come back here every chance you get, daily if possible. I do. Also it is a good idea to google "bipolar support groups - name of your town and state" and see what you can find. Calling your local hospital and asking if they have a BD support group is also an option. My local hospital has one that meets once a week. This problem of nobody understanding is common. Only some medical professionals and people who have it understand it and can offer emotional support. And you can also learn how to give yourself better support on this website. I hope you can meet people here and also maybe someone in your location.
Good Luck!
