Sometimes it takes a few minutes or in some cases a whole semester to feel people out and learn the kind of people you want to be around. I would still agree that doing random roommate/suitemate assignment worked out for the better for me.
While I am not super close with my roommate, we still get alone. We help each other with problems and talk through stuff but don't hang out.
I don't think you have to be best friends with your roommate from freshmen year even though that tends to be a pretty big trend.
But it took almost the whole first semester to figure out that I do not jive with one of my suitemates.
Sometimes it takes a hot second for peoples personalities to come alive. Normally I can handle people well, but my suitemate is another story.
I know you can't help anxiety but, we all suffer from some form of it, and she just takes it to the next level. Once I came into the room, with my other suitemate, and she was crying and angrily told me to leave the room when I would normally sit in there watching T.V.
But we had to be locked out of the room for a few hours while she emotionally broke down.
College is also a time to have fun, but also get your degree.
She is so wrapped up in the academic side of college that she judges anyone who wants to go out and do something fun. You can't just be wrapped up in your room all day doing school work until you die.
Also, she has failed to make any friends besides the people she lives with because she refuses to leave the room. I don't want to be judged every time I go out to do something that may be a little risky.
She also tends to jump to conclusions and get inside of her head a lot. There is a certain point when you can be around someone anymore. But patience is critical, and I'm definitely practicing my tolerance.
