I have the same issue, you aren't alone.

I even have a problem keeping my current circle of friends because they don't really like the "real" version of me. They much prefer the "okay" version of me that would fake smile and happy because it's not convenient for certain people and family members to see the real me which is at times manic and at times depressed.

I wonder if my issues with social circles and friends are mine or if they are on other people. I often fake happy and my family and friends love me, say I am great, etc. On those rare occasions I can't really help but let the real me out (when I am manic or depressed) they don't like that so much.

I can't offer support on how to make more friends, but I can offer support and say you are not alone with this issue.
