Is it normal i don't keep friends?

Alright well at first I thought I just don't fit in with nobody but as it kept happening I realized I was blind and it was me who kept pushing them away. Of course not all the groups I was with were as welcoming as others but that's just it; the ones who were welcoming I couldve still been friends with them. Unfortunately, my nerves get the best of me and I just can't stand being with the same people over and over and over and under and over again listening and tAlking bout the same stuff, I get bored plus I like meeting new people and say bye afterwards. This is a problem since I've always wanted that group of friends you always go out with talk to, you know your "click" I guess. But how am I ever goin to find them when I can't be with the same people for a certain amount of time? It's complicated and sucks cause I couldve had that group already but there's just somehing about me that doesn't go with the group flow but rather more of an independent mindset even though I long for that group or at least one decent good friend. All I can say when I walk away from "friends" is oops? I didn't mean to but my nerves take over me like insanely and instantly, I'm just like wait why did I just give her attitude? Oh yah I was annoyed well there goes that friendship...
