I have had ECT treatment twice, each treatment being a number of shocks. Many years ago. They messed up my brain for awhile, but certainly not two years! That is not right.
In my case it was totally worth it. I was never quite as mentally sharp as I had been, but I got along fine. (I started out with very high IQ and the treatment knocked me down to normal LOL).
I second the opinion that you seek out a good neurologist because you should definitely be clear-headed by now
