Yes I have had chronic severe clinical depression for a long time (diagnosed 13 years ago). I took Citalopram for the first time last year for a few months. I came off to conceive. I just didn't want to take meds as I felt it masked the problem and didn't cure it. It can be done, it's hard work but very rewarding. I've had a fair bit of CBT which helped and cured me of an associated anxiety state.
In the end I took Citalopram as I just decided I wanted to do the AD thing and give myself a break. I will go back onto when I can but only because I am happy to do that now.
You need to be a strong person to succeed without meds, that sounds like a bit of a strange thing to say to someone who has depression but if, underneath all the crap you are strong you can do it. I suppose it is a bit like saying if you have a strong immune system you can fight an illness without medication sometimes.
Good luck, don't be pushed into doing something you don't want to do. Sounds like you won't be pushed though and thats a hopeful start if ever there was one.
