I sometimes feel like this too. I tend to justify remaining in my current situation by saying.."I don't even know what a healthy relationship is so its not likely that I would find one or know how to create one."

This statement also makes sense to me. Sometimes I get this feeling that reaching out and sharing myself more openly with others is actually how I am going to "heal." That healing will never be complete and that there are other people out there that I am supposed to collaborate with so that we all move a few paces forward.
