Don't stress about the details. This is usually a long process. Potentially months/year. It doesn't cost them anything at this point to wait it out seeing as they've already paid your tuition this year. You will likely see a military physician/s and do a lot of paperwork. One day they will tell you that you will get a waiver, and the next they will tell you they are working on medically separating you, and the next they will tell you something totally different. Don't lose any sleep over it. Just wait it out and focus on school.
