Sorry , I dont mean to sound harsh but I think maybe you are naive here. A good nights rest did absolutely nothing for me. I could be wrong but I think that would be the general response from anyone who experienced depression. If not apologies.
I agree with Sparticus. It doesnt help, but you cant go without it either. The most difficult part for me is trying to get the right medication, have tried three different ones so far and its not helping. Prozac worked but that made me completely "dead" like Mila said you loose yourself.
