Can't think of anything to say

I know small talk is often necessary to start getting to know someone on a closer level, but I'm terrible at it. It's probably why I could never form anything beyond a superficial acquaintanceship with most people. I just end up creating awkward silences and eventually give up after having to carry the entire conversation myself.

Also, I am far behind in life experiences from my own peers so there is not much I can relate to with them. I can't talk about relationships or other things most people my age have experienced at least once, and I can't go anywhere much since I don't drive and can't afford a car (So being poor and without one is another huge obstacle).
