My story (Kinda long sorry)

I jave always been awkward and weird. When I was a kid it didn't matter because I had friends and tgey always indulged me in my weirdness. But as we grew older they sort of made me feel like a DUFF. They were better liked by people and they got other friends and I became that awkward girl that's always following them and people would only talk to me only when they wanted to talk to them. Whenever we would disagree on something and I would then later apologise they would make fun on me and read all our texts out loud and people would laugh at me. Luckily for me I vhanged schools but there I became really untrusting of people and I would fear punlic humiliation to the point where I stopped trying to make friends and now I am an adult with no one to talk to and that makea me feel even more lonely. My sister once joked around said that maybe I have Social Phobia and i looked it up and it is a real thing and the symptoms are exactly what I experience and now I'm just lost.
