I had to use SSRI's when it got bad, fortunately for me they worked - but it was always tough getting off of them too since I still had Lyme at the time and the depression would cycle back in.
I know that some people are having success with SAMe - a natural supplement. Although you would need to check to see if there are any interactions with the Nortiptyline.
Remember, we heal from this. Hold on to that thought. Each of us seem to have our own paths to follow in symptoms and treatments, but one thing is for sure - we understand the agony. Come here and talk. Find a face to face support group and see if that helps. Keep on keeping on - as we used to say. There is a way out of this.
