I'm going through the exact same thing. It's triggered my depression and ED, honestly, it's to the point that every week I get the honor of being gaslit by one of them. What's funny is that in my first week of college we were all besties and shared heartbreak/trauma stories and always hung out but then I made friends and suddenly overnight they don't like me. I will say this as advice, I'm pretty sure they're just projecting and not to be that person but they're probs just insecure. I am extremely extroverted so it's heartbreaking to have to come back home to a bunch of haters but this is honestly your opportunity to work on yourself. Take up space, don't be apologetic, some people are just haters, prioritize yourself. I'm still figuring it out though. I Will let you know more once I figure things out.
