Fatigue

Hello, I was diagnosed with anxiety and depression last year. I was on Lexapro for 2 months and weaned off it on the third month because it made my depression worse. For a long time I wasn't depressed when I got off my meds, but lately I've fallen into the hole again. I've been battling this nonstop fight ever since I was 5. All I'm asking right now though is how to deal with the fatigue... It seems to be chronic and it makes my day to day life harder than it already is... I got a job interview tomorrow but I'm scared to start working and go back to school because I'm tired from the minute I wake up to the minute I fall asleep. Any tips, advice, and help?
