I do not agree with 'forcing' you to share. That's not sharing, that's having something taken from you unwillingly. And that's not what sharing is about, in my opinion....
I agree with Anna about seeing a counselor. I see mine once a week and look forward to it. A chance to tell her about anything, something I can't do with family. And she has insight into my issues that is new to me, and it helps. Do see about counseling, if you can. It can be very helpful.
