Ready and now waiting

I'm new to this site, just found it today! I've gone through the 6mos of dr visits, etc, and have already been approved for gastric bypass. I'm frustrated with my surgeons office. I was on track to have surgery in May, but they dropped the ball by not scheduling me for the required pre-surg classes. Now I'm 10 wks out from a big vacation and still not scheduled for surgery. I was hoping to be 4 months post-op and able to walk better with weight loss. This really has me down and I've decided to postpone my surgery until Oct. I haven't told them yet. I'm waiting for the call to schedule pre-op testing and will tell them then. It took years to finally be mentally ready for this surgery and now I'm so unsure of what to do.
