Patience is key. I noticed a lot of people admitting that they bother their PEBLO or MSC frequently for information, and I personally don't see how that will speed up the process. During this time, you are still getting paid, you have health benefits, so just try your best to continue living the military life until the time comes. If you end up getting out, it will be difficult to plan because of the uncertainty of the process timeline, again, just be patient.
If you don't mind me asking, is your current goal to stay in the military or get out? Advice changes immensely based on that.
