It feels like half of my cohort doesn't like me
I started grad school this year and we are 2 months in. My cohort is ~15 people and we are pretty much all the same age, with the oldest being 6 years older than the youngest. Everything was fine at the beginning and I felt included (ish) but I still felt like I didn't fit in, especially with the people who I was trying to become friends with. We went to coffee shops a couple times and studied together, and then midterms happened and it all stopped.
Full disclosure, I feel like it might have been my fault because I have autism and ADHD so I might have missed social cues. Not fitting in has been a problem my entire life and I guess I am just disappointed because I was thinking "new program new me".
2 weekends ago, half of us were out to dinner and a bunch of them kept talking about memes they sent each other (they don't text me or send me anything) and even past and future plans that I wasn't invited to right in front in front of my face. On the computer of a girl who I wanted to be friends with (she sits in front of me), there was a group chat of some other people I wanted to be friends with, making up about half the cohort. I'm just lost because there is a discrepancy between how they acted towards me at the beginning before we started school and now. The only thing I have is one of them was nice enough to tell me that the others were talking behind my back about them being upset that I got distracted one day and was shopping on my computer when I should have been contributing to discussion (yes I know this is my fault).
The worst thing is besides that I don’t know what I did, and it just makes me think it wasn't one thing but I am generally not pleasant to be around. I also mask heavily, so maybe I started to unmask too much one day because I became cognitively tired but besides that I don't know. Besides those people, I don't really even have much in common (to my knowledge, but I am open to exploring) with other people. I feel like it's a bit late in the game to ask them about themselves because some other people also have little groups. On the bright side, there are 2 girls who I really connect with, so I think I am going to focus on that. However, I still feel like the other people have definitely talked bad about me in more ways than that. I wish I could just start over, and at the end of the day I probably wished I could be friends with everyone instead of just 2 for now. Is this normal and am I overreacting? Is there a way I can rectify my behavior or is it too late?
