I too have been a victum of meds stopping working. Been switching meds now for over a year and am just now having some luck with Prozac. Though I thought it was really working the first few days now it's dropped back off but not as bad as before.

I know that journaling helps. I used to do it faithfully, but got lazy and quite. I'm like you I have a hard time starting it again. I've found posting on PC has been a big help, so keep posting.
