mess up at work

I feel so embarresed today.  I had to go into work to drop off a key and one of the other employees said that I looked very bright.  I had a pink long sleeve shirt on.  I was joking a motion and stretch out my arms and said, "My shirt say's I'm here".  When I put out my arm I accidently hit another employee in the mouth.  Being the supervisor I feel so stupid.  First I feel stupid because the girl ran into my hands just as I was sending them out.  I feel bad for accidently hitting her.  Second I feel stupid because I was I feel like I was just trying to get people to like me and I was acting silly.  I feel torn because I know I shouldn't feel like it is not ok for people to pay attention to me, but I also feel like I should not let it keep bothering me.  So on the way home I of course had the urge to pull.  Of course righting about this right now as I write aout it I also feel like I want to pull.  I know I have to just keep taking deep breaths until it pass's.  It is just hard!
