I really sympathize with your situation. I remember this being very hard for me for many years when I was younger. I tried all kinds of tactics, like asking people if something was new. "Oh, I like your sweater, is it new?" and so on. I did that a lot as a kid and definitely didn't make any friends this way.

If I want to get to know/bond with someone, I usually try to share something that bothers/upsets me slightly, but that I think might be relatable. My goal is to tap into some topic that the other person really wants to talk about, but you broach it by making yourself slightly vulnerable so they feel comfortable.
