I think most of us here have felt the same way. Myself, more than others I'm sure. I also have depression and recently found out I am ADD. Like you mentioned I also knew there was something else wrong with me and just couldn't put my finger on it. I just thought I was airheaded and forgetful constantly. If anything learning that there is a reason for all of this gives me hope. Now it is just finding the right meds to help. Don't give up, if you need to vent you came to the right place. Hang in there and keep us posted.
