You can basically live indefinitely in the SEA with US passport (Thailand, Vietnam, Laos, Cambodia). Find a in a nice liberal bubble with loads of other foreigners as long as you can make 2,000 usd/mo you’ll be quite comfy and free here.
I’ve long given up on being part of the core society and embraced the life in a bubble. It’s pretty awesome! Feel free to message me if you have any questions :)
I understand and wishing you strength with this 🙏
