After 6 months of waiting for my MEB it came back today to my disaapointment. I have been in the USAF for 15 years and 9 months. I was diagnosed with Crohn's Disease in Sept 2009 with Osteoartritis in knee due to ACL repair. (i can't run at all) Which my commander made me deploy 4 months after the 1st surgery came home after 3 months on the Deployment to another surgery to fix damage that wasn't allowed to heal. MEB said 20% severence pay with Discharge. Can anyone give me advice other than to go to Formal Board. Frusterated that after this long, I am getting booted with nothing, no retirement, a severence pay which will equal nothing and a complete starting over of my career. Any advice will be appreciated.
