Am I a Bad Mother

So i’ve been checking my emails a lot and my sons school email kept going to spam and i can’t keep track of them. Recently they had where it was a *No-Uniform but house clothes * day a charity event and they sent an email. I didn’t went through mails yesterday and i get loads of other stupid stuff mails too and i guess it skipped. I didn’t check it and i sent my son in uniform but others weren’t. I didn’t notice in morning either (everyone was in jackets) . I feel like i made my son a clown and i feel too bad. I have an other child (2 years old) who’s going through speech delay and both my kids have speech delay and i’m going through therapy calls and other things. He said something and i didn’t understand and now i feel so low as i’ve been trying and keeping up everything with their school projects, Meetings, Therapy dates and i’m myself studying for exams next week.

Please tell me i did not fail as a mother please. I’m making sure they’re fed, clothes clean and fulfill all their needs on time. I’m making sure they’ve healthy and mentally balanced health taking them

to football clubs, gymnastics and letting them have their own play time .

Please guide me in highly on anxiety and over-thinker. and high maintenance. It making me crawl and cry. My son seems fine he’s 4 years old . Guess didn’t bother him but i’m feeling so bad for this mistake.
