Sorry, I'm a doctor in my country, and the question is, was you following a comportamental treatment to during the past years?
I mean was you gooing to a psycotherapist?
The mental illness as well as PAnic attac, and All the anxiouns diseases, need a psycological approach too!.
Moreover I have my brother with chronic depression and I can say that the drugs alone really don't work!
Be careful during your lowering down, despite you are doing this with a doctor.
Be strong!
