You sound burned out. I had a familiar experience a few years ago. I was extremely tired of my job. It wasn't a hard job, but I didn't connect with my coworkers. Also, I didn't find interest in what I was doing. So, it was soul crushingly exhausting. Btw, I'm not putting all the blame on my environment. It was as much me, as it was them.

Anyways, I took some time off to travel and unwind like you. I remember the day I came back to work-- all the stress and horrible feelings I had immediately came back like I never took a break. So, I left.

I didn't quit the tech industry, but I took a year break from working. I was lucky, because I had a SO that could support me. So, I didn't have to worry about money too much. I still missed the stability of a job though. The break did a couple of things for me. It gave me time to develop new habits and it renewed my curiosity. I started tinkering again. It's really hard to care about new developments or technologies when you're drowning. However, if you're able to take care of yourself, I believe you'll find the curiosity that led you down to being a developer in the first place.

If you're a developer or if you're in tech. You're constantly learning. If you don't naturally like learning, it's going to be tough.
