yes you feel tired, because you're mentally tired. I feel the same way. But working on yourself, and trying to get to know yourself better is a super hard procedure, where you have to change some of the fundamentals of the way you have been living your life so far. So it's very hard. but on the long run I would compare it to a moth turning into a butterfly. imagine that could hurt too, but look at the outcome! Zoloft will help you maintain that hope. I promise
good luck! hugs
