Same thing happened to me. I was originally scheduled for 5th of May and because of some stupid bureaucrat screwing up I lost that spot and am now rescheduled for September 20th. I was heart broken, depressed, pissed and then back to heart broken but now I've decided I'll make myself feel better by partying my butt off this summer. It won't make up for having to wait another 5 months for my surgery but I figure it's better than feeling sorry for myself for another 5 months waiting for my surgery 🙂
