Can you see yourself getting out of dc entirely? Get into a different field? Would you be able to take a month or two off, regroup and start out with a whole different crew, different policies, etc.?
Burn-out is a hard thing to deal with in this job because there is just no escape. It's in your brain, day in, day out. It becomes your life.
If you can narrow your burn-out down to the major issues and reinvent your job somehow, it can work out. If you can find some inspiring and motivating classes to take, that can help re-energize you.
I've bounced in and out of burn-out so many times I lost count.
Let's face it, dc is not a glamorous job.
And it's draining. Take care of yourself first so you can take care of others.
