I'm thinking of ditching out on rooming with a friend for next school year
Why would you want to ditch out on someone?
I'm afraid of sharing rooms because of my noisy room mate, Tyler.
I see your point, but you should keep your promises to friends. It's not nice to ditch people.
You being a girl doesn't really help here.
You should at least tell your roommate that you are planning on switching up. This is something that could really ruin their plans and their living situation for the semester.
