I suffered from depression when I was 18 (I'm 27 now). I took antidepressants for 4 years. It really helped but not with my energy levels. I get mood swings now but nothing major. I do get anxiety...
I have suffered from extreme fatigue since I was a child. From the day I was born my mother said she would have to wake me up to feed me. I will sleep 18 hours a day if I didn't have to get up....
