I did a 10 day retreat after burning out working at a hedge fund and I can highly highly recommend it.
I must warn that it’s not easy. I thought a meditation retreat would be a great way to unplug and take it easy but the schedule is intense and meditating that much requires great energy and focus.
Highly recommended but know what you’re getting into :)
Those courses are great! Regarding commute - there are ride shares available, especially if you come from a major city. And there is no need for special white clothes! (Although I'd avoid really extreme colors, logos, etc.).
I have a health resource, stemming from obvious stress hormone reduction.
Its a Sunday morning here; i will leave you for now with a registration website for a 10 day course: https://www.dhamma.org/en-US/courses/search
(It is near free, fees are commute, white clothes and a very optional donation, finishing a course is considered payment enough)
