Thanks everyone. Basically, I'm capable of sleeping 12+ hours at once (which I manage to do on the weekends) and I always wake up groggy and tired. I'm having a hard time focusing, my short term memory is horrible. I've also had digestive issues which have led to no diagnosis. The woman who gave me this diagnosis is a medical doctor - not a mental health person. I have a psychological evaluation tomorrow. She's sure it's because I never adjusted properly to grad school. I just feel lost because I've been trying to eat right, exercise more, and spend more quality time with my boyfriend and my friends but nothing really seems to be helping the physical symptoms. It's hard because I don't necessarily feel depressed so I don't know what to do.
