You're spot on! Letting go is the essence of meditation - raising above to a new level of reality etc. In terms of meditation, it's never good to overdone it. Sometimes I tend to seek an escape - but it makes me overthink if I was left with my own thought for too long. It makes me even more anxious. l I've found that exercise is a great way to help with stress because it discharges some of the ​nervous​ energy and increase dopamine.
