Missmoonshine - To a certain extent you've hit the nail on the head.
I tend to withdrawl just about entirely from everyone, but have one or 2 people who I mail or sms regularly to help me when I'm down. It's just that I tend to feel I overload them with my problems and they get frustrated - realistically there is nothing they can do for me, other than offer support. and How, other than saying: I'm thinking of you, I'm here for you...?

I just don't like to come across as clingy, selfish or needy, yet at the same time feel so helpless.
