I've battled it myself since quiting drinking. Just when i think i have it beat it creeps back up on me. I liken it to my head getting in the s***house as i put it. I'll get stuck there and wonder how i got to such a LOW POINT again!! I can think of various reasons forgot my vitamin or wtvr but it still happens now and then although incredibly less severe. I too tho got to thinking is this always going to be this way for me? I'm not on meds terrified of the possible side effects and such but again sometimes i think maybe I should just go see a doctor.
Sometimes i wonder if its the whole pesimist or optimist thing some are one way some are the other nothing wrong with that its just how it is. But I keep trying to turn myself into an optimist maybe its just meant to be? But i keep trying anyway maybe I can become an optimist?
Focus on the bright side as best you can that helps me.
