I may have made the hugest mistake

Yall… im an emergency certified sub and have been quite successful in most classrooms. Schools have told me im their go to person when someones out and its made me feel so seen and rewarded (im a masters in elementary ed student so this makes me happy that i get this feedback). One of these schools apparently had a bunch of teachers hyping me up and the primary special ed teacher reached out to me and asked me to long term sub for her while on medical leave. I was skeptical since ive only done gen ed but she reassured that I would be great based off the fact that I really care. Most of her previous long term subs would just read while paras did the work which id never do. After multiple meeting with the principal and lead teacher, I was convinced that it would be a challenge that i was up for.

Boy was i wrong… it’s day two and my soul is literally leaving my body. My back hurts, I already am sick since im basically working in a petri dish and GREATLY overstimulated. I am trying my best to be patient and take things one step at a time but good lord its much easier said than done. All morning the kids have been so disregulated cause we are fresh off break—there is so much screaming and touching. This is just not for me and im freaked out—do I back down and talk to the principal ab this? Do i push through? Im getting a gen ed cert which I literally vocalized prior to accepting the role. Im just such a people pleaser and i 100% shouldve said NO
