I have experienced it but have been able to ignore it.
the worst, I think, is the unspoken dynamic that it must be kept secret in some areas of life.

Like for instance, my sons friends families and families on his sports teams. We are with these same people most of the year and its not really their business anyway but if I was to tell them the repercussions would be ugly.
sure not to my face, but in ways like keeping their kids away from me so in turn keeping them away from my son. Shunning if you will.
After recent weeks of having some issues I would really love to tell them
"listen, I understand how I acted and things I said and emails I sent were weird paranoid confusing and offensive but I was having somewhat of a bipolar episode and I'm sorry"
but I cant and it sux
