OH my. I don't suffer with bipolar disorder..but I do have PTSD and all the stuff that goes with that (depression, anxiety etc)
No one in my family understands yet.

I was disabled in an accident 19 1/2 years ago... and they still don't "get" it.
I know my "friends" disappeared for the same reason. Plus, the frustration of the friendship, well it was just too hard to be friends with me. (I also suffer with chronic pain.) I am "high maintenance."
I do my best, and keep going. Worrying about their ignorance, or being angry would only hurt me...
