You're going to be asked about the gap in your resume. If and when an employer says "What have you been doing for the past six months?" You should have a satisfactory answer prepared. They aren't trying to make you feel bad, but if you say "I got burnt out and quit," they will most likely want some valid reason to believe that you will not burn out on them and quit halfway through a project. Their chief concern is making sure that the work gets done; if they hire a person who will leave partway through, then they have to hire a new person who will have to figure out your old work before they can continue. It costs them time and money. You need to figure out how you'll convince them that you will not cost them either of those things.
I think a good answer is to avoid discussing the burnout. Talk about skills that you developed during that time off and that you focused on. They do not need to be computer-related. If you can demonstrate that during your hiatus you learned to handle project management better, or that you had some unlikely-to-repeat personal matter that you resolved (family matter that they can't really pry into) I think that would be a good reply.
I'm sure that they will also want to be sure that you're up to scratch on your coding. Take a few review classes if you need to. Dink around on HackerRank and up your score there a little bit.
I'd also interview with a few places you don't care that much about first. Go for some company that looks terrible, or that's too far away, and get your bad interviews out of the way. I'm sure that they'll ask you some questions that you're uncomfortable with or that I (and you) had not considered. This gives you the opportunity to stammer and give terrible answers without consequences. Then you can go home, brush it off because it wasn't a job you were seriously considering in the first place, and come up with a good answer for when you interview with a company you're more interested in.
As far as how you're going to proceed in your personal life-- I think it's important that you establish the social circles and steps that you're going to take to avoid burnout. It's important to have a life outside of work that extends beyond solitary activities and includes some form of exercise. Find a therapist that works for you, join a rec sports team, find a running club-- something to ensure that you have some form of social and physical interactions beyond work.
