Danilee - here is a true story:
On April 29th of this year (I remember because it was my sister's birthday), I came to the height of a 4 month episode of DP and DR. Nothing seemed real - not me, not the world.
I finally broke down and told my girlfriend what I was going through. She was totally supportive, and I even went to the ER that night because I literally thought that something was majorly wrong.
Well, they didn't quite understand, but they did give me Ativan, and made an appointment with me to see a psychiatrist (my DP/DR was non-drug induced. I have been wrestling with it for over 12 years - I am 29 - due to a traumatic childhood).
Well, the psychiatrist changed my dosage of Paxil (up to 20mg from 10) and put me in psychoanalytic therapy. I finally put all my demons out there and conquered them. I am going on 6 weeks of no DP/DR.
My point is that for how low you feel now, this is how good you can feel soon. Never feel as though someone will commit you for going to the ER. People who need to be commited never recognize there is a problem. Visiting an ER on your own usually signifies a rational person, unless it is for suicide tendencies, in which they will commit you.
This disorder unfortunately is being too aware. Not crazy, just TOO sane.
Hang in there - get some therapy and get on the right meds. You will do just fine.
