This is a good thing you're going through. Yes, really. It's time to trust your instincts and remove the shyte, the cruft and unnecessary burdens from your life. "This shit life, we gotta chuck some things," said Michael Caine's character in the movie "The Weather Man" [1]. (Highly recommended)
But, my friend ...
Step 1: Stop calling yourself names. Please stop. You're not impressing anyone.
Step 2: Reach out. You may have "burned many bridges" but I'm sure you have one friend who you can talk to. If you don't have this friend, pick up that phone and chat to Dad or Mom or your guardian (hope they are alive). Those are fireproof bridges. Time to use them. Say exactly what you've posted here. Including the name calling of yourself. See what they say. Time to belong again.
Step 3: Time to spend more time with your kiddo, with homework and projects and play. Time to become a kid to be with the kid that matters the most.
I pretty much burnt out at age 39 too and quit a lucrative contracting job. Everything else besides the money was crumbling around me. Poor health (packing on weight in the middle), steadily increasing my drinking habit, distancing relationship with the wife and kids and lack of perspective on what I wanted to do with my free time and career. I changed that one day after I couldn't take the drive to the office. Stopped at the roadside, thought for a bit, turned the car and headed back home. I phoned in sick and later that evening wrote an email that I wanted to take some time off. Like permanently. I spent 6 months doing absolutely nothing from an earnings point of view. I joined the gym, I spent time with wife, learnt how to reconnect with my eldest teenager and took activities with my youngest. I even flirted with the idea of a startup. Still flirting... :-)
I have hobbled, tripped, fallen, injured, suffered and then recovered after 5 years on the income side but I have emerged on the whole a bit wiser, a bit bearable (ok, debatable!), a bit forgiving (mostly of myself), a bit less volatile, a bit accepting and a bit fitter. I cherish mostly what I learned about myself: that I can tolerate some things and some things I cannot. I now know instinctively whether a movie is worth it in the first 5 min just as much as I can tell whether a gig will be mentally and emotionally nourishing for me or not before I start it. It ain't just the money. If my instincts say no, I walk away. Chuck some things. This is what you are developing now. A sense of what matters and what doesn't. Don't fight the learning process.
Take care, Little Prince!

(Don't go by the hopeless IMDB ranking of 6.6. That's a travesty for Gore Verbinski's work of art.)
