Fear of letting go?

So, I've come to the conclusion that I crave human contact. Crave being around people and being a part of their social group. I used to dislike it, but now I'm addicted to it. I'll constantly tell my friends I love them - either that or tell them that they ARE my friends. And I hug people every chance I get.

And I didn't know why. Why I had this innate need to show my affection for others. I suppose you could just call me clingy, but maybe I have some subconscious thought that causes me to be clingy.

Maybe, I'm afraid of letting go of people. Of losing them as friends. I've had at least a few close friends that have drifted away so far, I feel I have no chance of ever getting them back. And it hurts a lot. Oh, sure I have new friends, but that's the thing. I'm worried it'll happen again.

That makes sense to me.
Besides, I really do love all my friends and I really hope they appreciate me telling them it.
