I have several conditions which require an MEB as well (PTSD, TBI, various neuropathies etc) One curious note, the VA already awarded me 80% while the AF still dicks around with the case.
The key is having the MEB initiated. Do you have a DLC / AF Form 469? Have you been on a profile for a year or more? Do your conditions fail retention standards. What you are experiencing is very common and it is a huge advantage to fight to stay on orders. How you approach this problem depends on the circumstances of your situation. What does your Doc say?
