Wow, what you describe is what happens to me exactly! And, that's what's so frustrating, you can't work out if they are busy or lying.

But, I also always think, why can't I be that friend they go shopping with for example?

There always seems to be someone already, and I am not needed in that same capacity. There is no room in their life for me. There seems to be no room in anyone's life for me.

I know I'm not entitled to be in their lives, but, I just wish I could be that person in someone's life, that close, that important. I know I don't deserve it, I just wish I knew how those people managed to get so close to the person I want to get close to too. I'm sorry guys, I know I'm really pathetic.
