You sound a lot like me.

I live with my bf, but it seems he is always preoccupied with work and his mates (Who are also work colleagues) and I manage to feel terrbily lonliness, even if I'm sitting right next to him. He is not the most emotional person, and getting the message about how i feel across to him is really not easy.
And all I yearn for is some understanding and sympathy, someone to hold and love me and say a word to make me feel better.

Lonliness and insecurity is so hard to deal with - ask me. It's one of the reasons I am really considering going to see my psychologist again, I feel meds are only part of the solution
