I am injured

I am so mad, I was 10 mintues into my work out this morning and pulled a muslce in my leg so bad, I can bearly walk.  What am I going to do now??  I guess I might have to jump into my ice cold pool and do some laps.  I really don't want to seeing its so cold and rainy out.  But I am so determined to lose these extra 25 pounds in my belly I will do anything.  Its all mind over matter.
