Do you share your feelings with others?

I am ashamed to say that I battle a lot with sharing emotions with people. I think I have been too hurt and somehow I have created a block between myself and other people. The hardest part I would imagine is when one blocks oneself from their own feelings. I do this. I am single so I cannot even share how my day went. Will I ever be able to change? I think that my blocking of emotion is holding me back from finding a partner in life. I seem very sociable but I am hiding who I really am. Which is an emotional invalid. I only feel safe showing anger?

I guess one would say go to therapy, but surely there are other ways of dealing with this?
