To: Lately, I have been really jumpy and anxious whenever I hear my roommate open or close her door.
Me: Have a talk with her and explain your feelings and how the way she closes her door is affecting you and ask her if she would close it quietly instead, so that she does not disturb you.
If she refuses to make change, time for you to find someone else to room with, who is more concerned for your welfare, than not caring about you at all.
