So sorry. I can't offer much help but I too have the type of mood that says I can deal with the manic and it's no problem and I'm not and neither are they sure I'm bp but it's the depressive that so suddenly knocks you down that horrible. I relate to that. I understand. It just comes throughout the body and not just an emotional thing that happens. So tough to help yourself. I know that if I can get doing something physical that that helps. I happen to love exercise but when this happens I have to drag myself to do something, bike, walk, etc. Going outside and finding something to do will help also. It doesn't take away the bad but it makes it manageable. I'm sorry I don't have too much to offer other than another person who understands and has had a tiny bit of experience with this.
Please have some hope.
