My anxiety is really getting so much worse

I just did a little oopsie at work. Well i know it's not much of a big problem ( i think) but still you know i feel really bad.

So it's about my work schedule. So my schedule to come to the office for this week is Friday and i already came to the office on Wednesday without telling my manager. I thought it wasn't that big of a deal but then this morning my manager asked my supervisor about me. And i became really scared, like thinking the worse that could happen from that. I'm all fidgety, poking out my nails, feeling dizzy, headache, couldn't eat a single thing and my heart was beating like crazy.

"What should i say to him? What do i do? He must be mad at me"

And thankfully my supervisor helped me to explain things and of course, i apologized too! My manager is really a nice person. I thought he was okay with me changing my schedule without telling him but i forgot the part that he is a little bit strict.

Now i feel a lot calmer but my head still hurt a lil bit. I'm still feeling anxious tho thinking that i'm gonna meet him in the office next week.

See? I know it's nothing but it's also myself who making all of this so much worse!! Only thinking the negative part!! You suck so bad, ginger!

What should i do guys? I suck so bad.

You don't suck at all. We all make mistakes at work. Once I accidentally entered a student's paper grade as 0 because I lost the email she sent it through. Simple mistake, scary for sure when you realize you erred, but I fixed it and so did you. People mess schedules up all the time--there are so many moving pieces it's impossible not to. I'm sure your manager understands.

I am sure you do a great job because you worry and care about your performance and development. Everybody makes mistakes, and for sure you did the best thing in this situation: you apologized and recognized your error despite feeling very anxious. I am sure your supervisor considers this and that´s why he was very understandable too. Also, as a recommendation, you can use stick notes or a personal calendar in your room with your shifts so you don´t forget and cope in a better way with your work.

Don´t be too harsh with yourself, I am sure you are trying your best!
