Yepo. I was on a 72hr hold after a manic episode caused by a med interaction (Wellbutrin, took away the mild depression but let the massive anxiety run wild) and it was the worst fucking experience of my life. Literally just stick you in a program that doesn't give a fuck about why your there, just headcount they can bill for. I was perfectly fine like 2hrs after I got locked in and spent the remaining 70hrs climbing the walls.
0/10 Do not recommend. And this was in Massachusetts, a place wildly known for good healthcare.
Man, I am 38. When I was in highschool I was in an alternative curriculum Math program called IMP, and it is/was literally what your talking about.
Instead of memorizing equations we were instead given a hypothetical situation and learned to solve it socratically both through conversations as a class with the teacher, and in small groups to try and figure out how to solve it. It made me love math so much I almost made it my life, it was literally everything I needed as a severely ADHD teen. Everything was a puzzle to be solved, and when you solved it you gained not just knowledge, but the perspective to know where the knowledge applies.
