Feel like an idiot?!!??!!?

Okay so a few days ago at work I started off badly because I came in and realized that I hadn't clocked out the night before like an idiot and then I realized that the manager who I'm pretty sure doesnt like me was working so I immediately got a stomachache but thankfully as I started working and getting things done I started to feel better.... Unfortunately at the end of the day I began to act like an idiot again after I clocked out I ended up going up to the front and one of the insanely gorgeous girls that works there, the manager that doesn't like me, and another guy were all standing together and I came up and stood in the wrong place at the wrong time and then tried to open the locked door in front of all of them so I'm sure they all now think I'm an imbecile!! I know it doesn't sound like much but I can't help but feel stupid and like things like this don't happen to really pretty girls. How can I redeem myself to these people and also how can I make myself feel better cause I feel sooooo dumb right now!?!?
