depression
"Young male early 20s. I suffer from major depression as well as anxiety. I tried 20mg Prozac only because it supposedly gives people more energy. The first 1-2 weeks I experienced side effects such as extreme fatigue and increased anxiety. After 2-3 weeks I began to feel better, however, it worked until it seemed to stop after about a month. It still helped relieve my symptoms slightly, but I had returning feelings of fear, panic, negativity etc and never felt more energized. I stopped taking it and after 3 days immediately felt much better. I ended up switching back to 10mg Lexapro because it worked great for me. Prozac helped somewhat, but for those who struggle mostly with depression/anxiety, I'd try more selective SSRIs personally."
