You're so lucky! You get the opportunity to learn how to deal with the stress and uncertainty of life voluntarily at your own pace. That's great, and will help you in the future. (No sarcasm: I had to learn these lessons after getting MS my last semester of grad school which is the life version of learning to look both ways after being hit by an 18-wheeler.)

Something that I've found really helpful to remember is that human beings as an organism are made to withstand stressful periods. Observe how your body and thoughts react to the stress. Don't try to get rid of the anxiety: Acknowledge it. Planning can help as others have mentioned, but be careful not to fall into the trap of trying to plan for any eventuality: You'll be so busy planning that you won't get to heal from your burnout.

Accept the anxiety and stress and find out what activities ground you/calm you down. I recommend doing this before leaving if possible. The big thing is to learn to trust yourself and accept that the anxiety exists because you worry for your future - however, you're doing this for your future: If you continue on being burnt out it's worse for you in the long run. Your anxiety and stress is trying to protect you.

I wasn't able to just stop working, but I walked away from a 'good' job and worked retail for a while. Having the time to focus on myself, who I am, what I value, and why I wasn't happy before have put me in a much better place going forward. So that's where my advice is coming from - grains of salt etc.
