But I really don't know where to go from there....
Just know that after college you probably won't see them again, and you will make new friends at whatever job you land, which hopefully means shared interests.
What have they done?
Unsolicited advice from a slightly older dingus: it's okay to make bad friends because they offer perspective and can help you grow. College friendships seldom endure so you might not have to worry about them for much longer either.
What's important is that you stay a good person in your own eyes and learn from this rather than go with the flow of the shitstream.
Think about this: is there mutual appreciation and if so are your current friends good company?
If so, be grateful you are in good company.
"Good company" = people who help each other out.
More depressing perspective: I look at the world around me and think about whether or not most people are good people... apply said logic everywhere... apply said logic to self from other perspectives... etc.
You'll outgrow some of your friends or realize they just aren't someone you want to be associated with anymore. There is nothing wrong with letting them go. It can be awkward breaking off friendships, but you shouldn't let other people hold you back or stifle your own growth. Life is too short to be bothered with people you don't think are good people.
Never listen to my late night profile posts.
Anyway, they didn't do anything specific, but sometimes I just think some of them are not good people. But that's fine, I still like hanging out with them, and after college I will be with new people anyway.
Don't stress it too much. I know plenty of people that got their shit together and became better people. Some didn't. You're all still young. Just don't let it drag you down one way or the other in the meantime.
Everyone is a bit into themselves in college. Easy to fall into narcissist traps. Avoid those people who fall into those traps and learn to recognize true narcissists.
Also to be fair, at times I was a bad friend as well, like when I dated my roommates ex when he was clearly not ok with it (but said I could initially). Funny thing is now he is one of my best friends...
