My life is messed up.

So l am a freshman, I am social, reaching out, talking to a lot of people where i share similar interests or similar social circle. But here is an issue, nobody gives a fuck about me, i exist or not. I dont know why but no one invites me to anywhere, a lunch or a social event, no one really dosent initiates any convo with me and when they do talk to me they want to get away from me, Dont know what sin i have committed to be treated like a second class person. I only few options left, i have been good at studies/work; but this thing has been killing me from inside. A simple "how are you", let's talk or do you wanna hangout, is all i need, i need to feel accepted into this environment. I have been made to feel to be an outlier.
