So I had one major psychotic break and that was thought to be triggered by stress...specifically social anxiety. I got cbt therapy and that helped a lot. In my case the cbt was also tailored toward psychosis but we dealt with anxiety as well. I mean you still need an antipsychotic so I hope he gave you something for it but once you are stabilized you can start dealing with what triggered the break/hospitalization if it was due to stress/anxiety.
