One day, I went to reach for my son's doorknob, and the next thing I knew, I was trying to get up off the floor. It's like I just passed out; when I noticed I was on the floor, I was wondering what happened. That has happened to me several times. I've had every test, and the doctors still can't find anything. This has been going on for about 4 years now. My last episode was last year; my son saw me in the garage. I never know when it's going to happen, it just happens. I don't feel any strange way before it happens or nothing. I tried getting a service dog but can't afford one. Has anyone else had this to happen to them? Could I get a service dog without paying to get it trained? This is scary to me. I need help.
