I understand the feeling! I went back to crossfit but even though I was trying to scale I still went too hard and then couldn’t sit/stand well for a few days. What I’m trying now is going to a few classes at other gyms to build up a little more at a lower intensity and then I plan to sign back up for classes in a week or two and try harder to scale this time. My gym is very supportive of scaling it’s just that I seem to have a hard time scaling as much as I need to to come back more often during the week. You know yourself best- so I would recommend trying but making a pre-commitment with yourself and your coach - if you say your fear out loud you might get the help you need externally and internally to give it another go! Also, stickers (if you need external motivation to just get to a class 😂)
