Oh yes, exactly what Dee said is true for me. I finally got started on antidepressants just before I stopped drinking. I have been taking them for years and don't intend to or feel a need to stop. My depression started in my early teens and I didn't start antidepressants until my mid-forties. I no longer fear going to that 'dark place' but at the same time, I know I have to work at staying positive, too.
Good luck with the new medication and good luck on your new job.
