Should I make friends in college?

Of course u should! you always need to have someone with u to support u even if it is one person. Friends are there if u need them and if u decide not to and u have a problem then who will be there for u. Some people might say ur parents however some stuff can be confidential and u might not want to tell them about it so it is always good to have a couple of friends. however whoever u choose to be friends with, make sure they are the right people to be friends with and dont affect ur life in a bad way

friends should be the first things you look for when you are in new places. Forget if you had a bad history in the past, this is a new chance and you shouldn't let past things make you alone. Remember though, you might not be the only one looking for friends, so try and be as friendly as possible so not only you will be FINDING friends, but you will also BECOME A FRIEND TO OTHERS

If you want to spend the rest of your life with no friends, then you can start now.

But it doesn't sound like you want that. It sounds like your "friends" caused you problems. Your college has a counseling center or medical center. Go there and see a counselor. A counselor will help you process what happened and figure out how to have real friends (not "friends") who will add to your life overall.

Not having friends has given you the time to think (too much) about this a year in advance

surely you have matured since middle school? enough to manage your time better?

if you havent, perhaps college and the workplace isnt for you

You already identified your introversion as a catalyst. I bet you have matured since middle school. Don't be afraid to succeed.
