I've been disliked my entire life no matter where I go

Well the title says it all. I've decided to finally seek some form of assistance for this. It all started in high school and I've never been able to figure out why. It seems everywhere I go, people dislike me. I have spent the better years of my life trying to figure out why, but to no avail. I don't know if I will be able to figure out anything here. I really don't know why I am even posting here. It seems futile, but I figured I would give it a shot. When I approach people, there is always this sense that they must think I am weird or unintelligent. That is my best explanation to describe their reactions to me. I guess I am wondering if anyone else has experienced this and has come to some golden realization as to what it was because it really has been eating away at me my entire life. I have never had a core friend group and most friends I have had never truly felt like real friends. I've never been able to be my true self around anyone. That's right. I have NEVER been able to be my true self. I feel like I'm always putting on a facade just to be somewhat accepted as normal. Trust me though, I have tried to be myself, and it never ends well. I am becoming so depressed because of this. I feel like there some level of learned helplessness here. Nothing I do works. Please help. I appreciate any help in advance.
