Lost many friends due to bipolar. Hid my illness from some. Actually put an ad on Craigslist to meet new friends. Wound up meeting two wonderful women who understand my illness.
Now I try to be as honest as I can with everyone. Have tried to give up lying and making excuses.

Best friend dumped me about four years ago...I was manic and hurt her terribly. Now she has come back in my life.
One thing I have learned is to have many different friends from different areas.Don't have all your friends in one group where they all know each other.

For me the best cure for losing friends was to make new ones when healthy. Then gradually ease them into your illness. True friends may need a break but if they love you they will come back.

Life is too short to mourn too long. There are ppl out there who can and will want to be your friend.
