Any thing I can do to stop the nightmares?

I’ve been struggling with nightmares, but my risperidone has been helping. However, last night I woke up in a panic and accidentally shoved my cat while trying to fight off my attacker in the dream. I honestly feel terrible. My cat was just starting to warm up to me, and we were cuddling the night before; she really helps me. I’m still on the waitlist to see my psychiatrist—it’s been 5 months. My primary care physician knows about the nightmares but doesn’t want to start me on prazosin until I meet with the psychiatrist. This feels like a new low for me, and I feel awful about what happened with my cat.

Is there anything I can do to stop or lessen the nightmares? Has anything worked for y'all?
