I share the experience of all 4 parents of this comment. It turned out I had undiagnosed ADHD. After diagnosis all my life suddenly made sense. Before the diagnosis, my situation had progressed to a point I’d get burnout by just everyday life, let alone work. Everything was overwhelming. Treatment turned my life around.

Later, I found out I have autism too - many autistic people “mask” around other people, altering their behavior to hide autistic traits. This is another thing causing (temporary) burnout after being around people.
