I am in my first year of college and have really bad social anxiety (just anxiety in general really). I feel depressed and tired all the time and have no energy, however much sleep I get. And even though I study, do all my homework (..just about) and try and focus and listen in lessons nothing is sinking in and my grades are pretty average- but that is with help and the internet and using my notes. When we have a test I usually do pretty poorly and i'm barely scraping a pass. I've talked to my parents about it on many occasions- and I recently got a blood test for hyperthyroidism and anemia but results came back fine. I am apparently physically fit but don't feel like I am. Is it mental? I have no idea what to do
