I studied NLP recreationally back around my last year of college in maybe 1999? as part of
http://www.pickupguide.com . That site along with the show Mad Men probably taught me more about relationships and the business world than I ever learned in school. Thankfully I was able to forget it and move on sometime in the mid 2000s haha.
Anyway, something related that has helped me immensely is Cognitive Behavioral Therapy (CBT). I had the worst burnout of my life starting a year before COVID-19 hit, due to some struggles with work and sleep apnea leading to digestive issues (leaky gut to IBS/IBD) I didn't know about. I woke up more tired than I had ever been, every single day, and my whole body hurt like I was hungover and getting arthritis, even though I was going to the gym.
Anyway, I got an appliance to fix my bite, isolated the problems with my diet to an inability to digest legumes and nightshades (see Dr. Gundry for more info), but even after doing everything right, I was still burned out. I finally isolated that to untreated ADHD symptoms that snowballed into severely negative self-talk.
At the time, I could barely get out of bed and brush my teeth in the morning. It was kind of like I had a stroke, and lost the pathways responsible for problem solving. I went through the motions of the chores I had to do each day, and switched from criticizing myself to repeating the mantra "I'm excited", since anxiety and excitement are experienced identically by the body. Any time I had a negative thought, I noted it like with meditation and set it aside, or actively reworked it into a positive spin on the situation, even if it was in terms of a positive outcome for someone else, or progress towards a long term goal of mine. Sort of a self-administered form of CBT.
I was able to learn new habits every 2 weeks or so, and finally recruited the rest of my brain to take over for the parts that had quit working. I started on the road to recovery about 6 months after the fallout with my work, and was effectively cured over the next 2-3 months.
The other main tool that finally got me out of the hole was to separate my plans from their execution by creating temporary todo lists. It turns out that I also had executive dysfunction from trying to hold huge problem spaces in my head for too long. It was like I ran out of room in my brain's hard drive and it began thrashing.
Now that I am no longer burned out or depressed, I've also noticed that the dormant problem-solving pathways have reawakened. So luckily I don't have to relearn the technical skills from before. I've been doing handyman work and spend a lot of time daydreaming about what I'd like to accomplish on the computer, so when I sit down to it, it's easier to overcome starting friction. I'm focusing on having no lost days, and treating every checked off item on my todo list as a victory, rather than criticizing myself for lack of productivity.
