It sounds like you are doing what you can...this is a very difficult time. (((hug))) Do keep talking with supportive friends and if there is a place out of doors you can go and relax safely for even a short time each day it might help. (or even doing exercises in your room, whether just stretching or aerobic....) Good for you for getting your first post grad job! Hang in there, this will get better...but it sure is a long struggle.
