I was that way for a very long time. I still am in regards to most people, even close friends. I only tell people what I think they can handle, what I know they will accept. As a result, I lie a lot. People ask too many questions sometimes, and there isn't another way for me to handle it. There are a grand total of 2 people I trust completely, and it took a while to get to that point.

I don't blame you for wanting to hide yourself. Sometimes it's the best way to survive.
