Make an appointment with a VA disability retirement rep. There is a lot to go over. To start getting your disability asap you need to have your claim filed at the 6 month prior point. There’s a calculation and a bunch of forms to fill out. Do yourself a favor and request your full medical record on disc tomorrow. Takes like a month to come back and then either fill out the paperwork yourself or hire a company to do it. Don’t wait till it’s time. You won’t see any disability money till significantly later after your service ends.
