I can't answer any of those questions, but can say you're not alone. I have intense thoughts like that out of nowhere as well. One day last week I was boiling water to cook & out of nowhere I thought what If I just burn my arm on the eye of the stove. Now I wouldn't do anything that drastic either, but it doesn't stop crazy thoughts from appearing. Good thing we don't act on those types of thoughts. Stay safe & take care *hugs*
