First Time - Can't Sleep Can't think!

i been working as a nurse for about 2 months now, still trying to get a hang of it. i got written up for the first time,recieved it yesterday! i messed up the admission papers., to make it worst the same day i got 2 admissions to do, like its just my bad luck!, i couldnt sleep, i couldnt eat, all i think about are the 2 admissions i had last night. i know that i am new and that this write up is a lesson for me that i need to learn. i dont know what to do, i cant think anymore.
You actually got writtten up? I mean a write up that goes into your personnel file? Seriously? Seems rather harsh for a paperwork issue. Anyway, nothing left for you to do but let it go and relax about it and learn from it. Easier said than done, I know. Hang in there.
yes, written up, that goes to my files, it is harsh. trying to hang in there. thanks.
