Without any doubt, in fact, that's probably a good sign that you need some external help (friends, family, maybe professionals) to guide you back on to the road to recovery. I've spent 3 full years doing nothing but manual work (metalworking, building a house and a windmill) because I was literally at low tide. Still not sure if it actually was 'burn-out' (no sign of depression afaik) but other people I know in my en…
Did working manual labor help you figure things out? I am seriously considering working a job such as the one you described part time to pay the bills after school while I try to build a freelancing business.
I worked my way through college, mostly as a bartender, and for a little bit as a janitor for the school. In high school I set up large canopy tents for a company. I learned through this that a lot of physical work is cathartic. I can get my frustrations out. I provides my body something to do, and my mind a trivial foreground task, so I can get lost in thought -- not the intense focus of solving a problem, but just a mind wandering, tangential set of thoughts. I learned how nice it is to be able to walk away without concern, without the work consuming my thoughts.
There are two different aspects of all of this from my perspective. One is the exercise portion, bartending can be a good aerobic workout if you let it. Particularly if the bar has good music, basically you dance all night. This really is a good way to "zone". The other aspect of it is the menial task as a gateway to meditation. I mentioned my good thinks above, most of these came sweeping or mopping. Mopping a mile of hallways at night, or cleaning up after the bar closes, provides this, and is a great way to learn to enjoy the quiet.
All of this is hard to get as a professional. I personally would take that job if I were you, just to learn about the stuff I mentioned. The skills have definitely helped me in my life. Anytime I feel burnout coming on, I have to stop and reprioritize. I don't have bars or universities to clean up anymore, and I don't go dancing much. Instead I apply these things to my gardening and yard. Mowing is almost as good as sweeping. So is pulling weeds. The exercise i get by going for long walks, or hitting the gym. Doing this stuff really helps me get centered, and allows me to be more productive than I would be without, even if I reclaimed the couple hours spent on it daily and used them for work.

edit: thought about, but forgot to mention: There was a big component of bartending: talking to people every day. I am a total introvert, I can go days without talking to people about something other than work. The bartending thing really forced me to interact with people in a social, general way. This is surprisingly important, even if it feels awkward/uncomfortable. At least a couple times a week I go to a coffee shop or bar and interact with strangers, because it really does seem to do something.
