I Was Started On 20 Mg Of Thorazine About A

I was started on 20 mg of Thorazine about a month and a half ago for anger issues. I have PTSD complex from abuse as a child and a wife. I now feel worse, am still angry, but more depressed and very paranoid. I am afraid to answer the phone or open the mail, a reaction I had over 20 years ago to Prozac 20 mg. I've done well on six .25 Xanax a day. My pharmacist advised going off the Thorazine as I didn't have the symptoms until I started it. I am 74, retired, with a heart condition, COPD, Barrett's esophagus, and severe osteoporosis.
