I had major anhedonia after my biggest psychosis event in 2015. It turned out that anhedonia was caused by Risperdal which was given to me during my inpatient stay to treat psychosis. When in 2016 an outpatient psychiatrist switched me from Risperdal to Geodon, anhedonia was gone and creativity returned full force within literally a couple of days and I wrote some of my best pieces, prose and poetry, that month.
