struggling to have conversations!!!! need help! long post!

So I have realized I am having extreme difficulties holding conversations/interacting anymore. Whether it be with girls, friends or strangers I struggle to have conversations. With girls I can't break the ice and if I do, I can't think of anything good to say besides the same old bland topics so i come off like a punk. With anyone else i can't come up with anything good to say. I always end up talking about the same things so when I am talking with friends I end up having the same conversations over and over. I notice it all the time whether they do or not. Its like I rack my brain trying to come up with conversation pieces and yet nothing. its like staring at a blank chalk board. i get nervous, anxious and then uncomfortable. It makes me feel isolated, enclosed, dettached... This even happens with my family! Its keeping me from making friends and meeting girls so i end up hating whats going on in my life and never being happy.

More on the topic of dating... I feel its something I lack and its like that one puzzle peice that when you find it, the puzzle will finally be complete. (Below i think is a link to a previous post about my relationship problems if it helps to see what else is going on in my head.) I feel if i could talk to girls whether its as friends, dating or even after dating it would be a huge step in the right direction!

Do I have social anxiety? Personality disorder? Can anyone shed light on my feeling of darkness? Does anyone have some good tips on conversation pieces or literature or websites along these lines? Any help or direction is SO appreciated!
