I have small fiber PN for over 11 years and my husband and I are on vacation with good friends and we r at Disney world - I found myself needing a wheelchair and slowing everyone down. I thought I knew my limitations but this was way over my head! Disney is so accommodating for wheelchairs but I didnt think I was there yet. Very humbling. I took the day off today with everyone off to the beach - hard not to get discouraged. Just kind a want to go home ----- understand?
