Thanks MickeyCheeky, I feel you may be right about disclosure. I think sometimes disclosure can help as long as it's with the right person.
I am lucky in that I can tell my husband pretty much everything- when we were first dating he said I was clingy, I guess that stuck with me, but it was a long time ago. We have talked it through many times since and he is supportive.
Other friends, some are closer than others, sometimes I feel I can discuss, sometimes not.
Perhaps it is about trust, both trusting others and trusting myself to make the right decision who to trust.
