Oh boy have I been there. And when I finally got my shit together and got my GP to write a referral, the first psychiatrist I called had a voice-mail informing me that he was off on vacation and would be back two weeks ago. That alone set me back a month.

Do you have someone close in your life? Like an SO, parents, roommate etc? If you can't focus on hauling your ass to the doc then maybe try opening up to one of them. That way there'll at least be someone bugging you to stay on the path of diagnosis.
