I've had a few 5150's sadly. I never thought I'd get through the embarrassment of each of them once I came down......I turned it into a much bigger thing than it needed to be....felt my life was ruined but it wasn't. If you are cold and uncomfortable there, ask for some warmed up blankets as the ER usually has some. Don't be afraid to ask for what you need for comfort. Wishing you the best.
