hi i am an 18 year old female college student..for the past week i have been sleeping about 9 hours a night but when i wake up i still dont feel rested. I tried drinking some coffee in the morning to wake up, but for the rest of the day I feel jumpy, sweaty, faint, shaky, and nervous. Ive stuggled with anxiety in the past but it s usually due to stress...My life isn t particularly stressful at the moment and I don t understand what s going on.
