I have a very difficult time trusting people to any large extent. It scares me. Just about everyone I've given that much trust to has changed. So I build up walls when I start feeling vulnerable. As far as I can tell, I have no control over it. I guess it's my body's defense mechanism to keep me from getting hurt. But it has it's disadvantages too. It means that I can't truly get close to people.

So I was just wondering, do any of you have this problem, or have you ever had it? Do you have any suggestions?
