Two years or one year doesn't keep you from re applying if it was service related.
Especially since you were given a rating by the VA.
Your rating won't be reduced by law, they only opt to increase if you qualify. That right there probably takes a lot of the
worry out of whether you should or not. You don't have to wait. I know a lot of vets afraid of the VA taking away what they
have, and have given up on their benefits.
