I, too, have trouble talking to ppl, but just let me touch the keyboard. So many like us have lots to say, but don't think anyone's interested, so we clam up. The truth is, I usually find small talk boring and fake, so I'm waiting for some good solid conversation. Most ppl I find, are afraid to talk real 'cause they think you won't like their ideas. Anyway, whenever you want to jab about whatever, just look me up, I'll be here or there :)
Sure, you seem like you need some people to talk to. I'll add you.
Why not smile, laugh, be happy & you may find it becomes easier
start by listening & understanding what people say to you & show an interest in what people say & it will come naturally
