Oh man, that really sucks, that your government more or less calls all the shots with the docs,pdocs, etc.
I didn't know you did not live here, hadn't read all posts.
I really can feel your frustration, and I am sending you some (((((((((((( Angel ))))))))))))

From being on SSRI's for a length of time, they tend to poop out, so that is why my doc started me with the Lsmictsl, though it is not an AD, it helps like one while at the same time it is still a mood stabilizer.
I'm sorry that the Lamictal didn't help you, I think you mentioned that was one you had tried.
Well, I'll keep you in my thoughts and I am sending you good wishes for a positive path to be found.

Sincerely,
DE
