@dicey I have not dealt with psychosis personally other than self induced via hallucinogenics on a few occasions, but I have dealt with severe anxiety and depression over a period of several decades which ultimately lead to some tragic actions on my part and over those twenty five years I was on SSRI's or NSRI's pretty much the whole time and to the degree they dulled anxiety they dulled the ability to feel anything at all. I finally learned a form of meditation broadly called Mindfulness meditation and within a month of starting to practice I dropped the SSRI's I was on cold turkey against the advice of my doctor and haven't had significant issues with either anxiety or depression in the 13 years since. Obviously, your issues and the solution is different than mine but similar to Mr. Nash's though in his case his big issue was that the meds extinguished the creative spark and his ability to work and earn a living rather than just emotional deadness, but the emotional deadness is certainly something I can associate with. I wish he would speak more on how he overcame his functionality in spite of his illness.
