I've been in my dorm room for almost a week now

I read this as "doom room"

Do you think it's depression, or is there some kind of situation that has you down in the dumps? Is it just a big lack of energy?

to much time alone can do that to you
but you will be back around classmates and friends soon
This too shall pass

I hope you can pull yourself together. Being closed up in a dorm is not a great place. I found it suffocating in there at least. Sometimes a good first step would be going to an isolated spot in a park or library and listening to some tranquil music. But I hope the mood you're in lifts and you can get back to your life.

put the phone down and go outside and meet some people.
and not just black people!!!!
meet some Asians! they are nice people!
