Any advice welcome

Hey guys, I'm just gonna cut right to the chase. My diagnosis is psychosis accompanied by Generalized anxiety disorder which means I pretty much have anxiety 24/7. I'm constantly in my head and lately it's been so intense I haven't been able to control it. Not by breathing, or using my 5 senses, it has been out of control. I have no more idea of how to cope aside from becoming medicated which trying to avoid. Anyone else been through this or have any suggestions on how to at least somewhat calm this constant state of chaos in my head?
