the truth about my parenting blunder

so i have a 4 year old son and we live in this small apartment. it's been kinda stressful with him starting preschool and me being a full time mom at home. anyway, there was this day when i got super annoyed by the mess he made all over our living room floor. so like i snapped, i just lost my temper. told him if he didn't clean up in 5 minutes i would throw away his toys for good. i know that's not okay but i felt cornered and it was getting too much. so i walked into the kitchen with a big garbage bag, thinking of throwing out some of the small stuff on top, maybe just to make him feel bad or something, idk. then he came running in crying, saying sorry for being messy. i felt like crap but my heart wasn't really breaking either. ended up putting all the toys back and promising it wouldn't happen again. now i am kinda scared of how much damage that might have caused and wondering if i should talk to his teacher about it or not.
