Black & Blue and sore all over

so I hurt my foot on Tuesday... did I say that before? Well I did... had a fight at 5 in the morning with the butcher block cover for the sink.. well yesterday consisted of "Take your child to work day" and I walked all over the plant with my friend Kelly and her two cutie nieces... I was "rent an-aunt" yesterday! We had so much fun but when they left I was so tired, my foot was sore and I had to recoup so I was in a somewhat okay shape to strip test in karate class! So a little before 5pm someone came on the loud speaker telling us to evacuate the building... I took my stuff and locked up my crib. After waiting what seemed like forever I finally left... it's was 5:45pm and I was sick of sitting outside and not be able to smoke (there were other people around so I couldn't just smoke if I wanted to) so I walked my ass down to karate class. The walk wasn't bad... I listened to my Ipod the whole way not paying much to anyone or anything except that one guy I crossed under the underpass, why did my stomach get all nervous I don't know but I didn't look down, I looked him straight in the face! Lesson One from karate, stare your possible attacker in the face, learn his facial features! If someone is thinking about attacking you and you can describe him 50% of attackers will not attack if they realize you looked at them. Then we passed, and part of me wanted him to grab my hair so I could go nuts on the asshole...but he wasn't an attacker, he was just a guy walking somewhere so I turned up my Ipod and kept walking.
Class was good, painful but good. I got my first strip on my brown belt, if my foot wasn't throbbing so much that tears were welling up in my eyes I think I would have smiled. I did my intensity form with power and my only mistake was my damm foot... I keep babying it, I do it without thinking so when I had to shift quickly into a deep forward bo, I lost my balance and had to regain control and jammed my right foot into the mat... in doing so I sent shocking pains up and down my leg, opps! The tears swell and I still am only half way through my form... I finish as quickly as possible, bow and sit my ass down, grab my foot and cry a little inside from the pain. My teacher told me I did well and he can see that I am in pain and it's good that I didn't just stop when it hurt b/c if someone were to attack me I need to be able to fight back, through the pain and get away. I was proud of myself but so much pain was disrupting my thought process. We went home and I iced my foot for almost an hour before finally going to sleep.
