Hi,
ok my mom had a simliar conditon(medical) as you and she was completely fine. So think positive you will be in my prayers. I've been hospitalized before for my panic attacks, and yes it is hard, i love being home and hate leaving it, i'm not what my dr says as a"full blown agoraphobic" but i do show some symptoms. this is what helped me when i was hospitalized, if you are going to be there awhile bring everything that calms you or reminds you of home like your pillow, a stuffed animal, pictures things like that. and i know the staff at the hospital will be very compassionate and willing to help you with your every need...good luck and best wishes.
