I need help handling my kid bro (we are 18yrs apart, did not grow up together) has or is bi-polar, and highly unpredictable, one day he is all friendly and the next he is spoiling for a FIGHT (today is such a day)! Ever since he was a baby I have tried to love him, be his friend, keep the door open to him (he is 45 and I am 63). Everyone else has shut the door to him, because of his out of control behavior! But, I just cannot go there! I would hate for someone to do that to me! So, I keep being there for him, but, my husband and I, are in the midst of our own human woes with failing health and a stressed out marriage. Frankly, I can't handle anyone who is out of control, and my brother IS! He can be highly abusive and intimidating when he is angry and in a tormenting state of his own.

Feeling overwhelmed and at a total loss. Any suggestions?
