I can understand how worrying and frightening that can be.
Suggestions
- tell your doctor, they might be able to adjust your meds to help.
- talk about it with your therapist, s/he can help you explore the internal conflicts etc that might be stirring things up for you.
- talk to occupational health/HR at work. They might be able to support you with reasonable adjustments in your work/shift pattern while the psychosis is most acute.
