When all of my other coping mechanisms fail, I take an OTC sleep aid and fall asleep. [NOTE: Please consult with your doctor first to make sure this is ok.] It’s not my go-to solution, but it’s better than launching myself into a psychotic episode that might last for days.
One of the best things I’ve ever done for myself is to get a cat. He calms me down when feeling anxious. Sometimes when I’m feeling manic, he comes and sits on my lap and I’m reluctant to move him because he’s sleeping. I also use him to check for hallucinations. If I see something, I throw a toy in its direction. If my cat notices it on his way to fetch the toy, that means it’s real. If he passes by it, then I know that it’s a hallucination. It’s not a fool-proof method, but in my experience, it works. You can check out where to find local shelter animals at Petfinder.com
