Sorry you're feeling so bad. Depression is really awful because it gets into every part of your life. Hang in there, there is hope that things will improve.

I think the list of depression markers you mentioned is a great start because it's specific and that helps doctors a lot.

I do something similar with my pdoc: I tell her what symptoms I have been having and how they affect my life.

I try to be as clear as I can without getting bogged down in the details. I only go into detail when she asks me about something.
