I've seen a lot of anger in people suffering from psychosis. I don't know if it stems from early trauma in which anger wasn't allowed to be expressed or trauma from the illness or if it's just anger from the freaking unfairness of the whole thing.

My son experiences a lot of anger and isn't particularly good at handling it. I always tell him not to suppress it but not to act it out. I think you're right you need to experience it - but without hurting yourself or anyone else by acting it out aggressively.

Just remember it's only an emotion. It won't destroy you.

Maybe you should consider the possibility that the SAM-e is contributing to the intensity of the experience. Like any antidepressant SAM-e can cause mania. My son often experiences mania as intensely uncomfortable irritation and anger. Maybe try taking 1/2 or 3/4 of the amount?
