Angela,
There is no doubt that you give of yourself to help others. You truly care and know the right things to say and when to say them. You are a huge asset to this sight.
I have not known you long enough to really give a knowledgable answer. I do think that often trust is a major issue in sharing of ourselves and past hurts can make us more reluctant to share with others.

I have recently found a person in the forum who I trust very much (you know who you are : ) and when you find someone you trust it does become easier to share.

You are a great person and a true friend would give you the time you would need to open up to them.

take care.

Kim
