I agree. I am bi-polar and also DID. So my experience may be a bit different but I'll try and help. Being bi-polar is such a strange feeling. One hand I am manic(cleaning the house, every inch of the house without a breath taken) Lately I feel indestructable, invincible due to my high mania. If your friend is in this state he may push you away because he soesn;t understand himself. If he is struggling with himself he not in a space to be with someone. I learned that when i was in mania I pushed away those I REALLY cared about and "dated" those just to get my needs met. Bi-polar is difficult not only for the one living it, but sometimes its harder for those who have to live with it.

Give him space, but don't forget about him. Show him you care and you're there to help. BUT don't push. we need to know that you will "get" us. Even at our worst. Hope this helps. I know I babble, hehe and thats due to DID and all the "stuff" in my head.

take care
