AIO : my friends never chose me

Am I overreacting : my friends never chose me

I 21F, i'm part of a friendgroup consisting of 7 people i met at university, we have been friends for a little over a year now. And i recently became aware that my friends do things for each other that they don’t for me. For example there was that one time where we wanted to go to a restaurant i loved, the 1st week friend A couldn’t go, so we said let’s go next week, but i had an appointement i couldn’t skip and asked them to go next week, they said no, they were tired of waiting. They could wait for A but not for me.

Or just yesterday, in class, friend A moved places to go charge her laptop, so she was alone. Friend B who was next to me moved to be with her so she wouldn’t be alone. The same thing happened to me last year, nobody moved to be with me, i sat alone.

If i sit at a table and other friends sit at another one (4 places by table), people first go that other table, or just like last time, a friend sat next to me, then the other saw we wouldn’t all fit together a the table, so they sat elsewhere, and she moved to be with them.

The same , when someone goes to the toilets before going home, WE wait for them, but last time i went nobody waited for me. And now I'm scared of going to the toilets, because if they leave without waiting for me, i know it will break my heart for good.

And finally this morning, 2 friends arrived together, and one asked the other if they wanted to switch places (one was obliviously bette than the other), and I just know they would never do that for me.

There are just so many little things like that that see.

So tell me reddit, am I overreacting ? Because I can’t stop thinking about all of this and my hearr breaks everytime.
