Good news and frustration

As with teaching lets start with some good news. Last Friday Grandmaster gave me my fifth stripe and told me to prepare for the upcoming black belt test. Of course now i'm so nervous and every class counts double in my mind. Now for the bad news, I haven't been able to get to class much because I've been working uptown and by the time I get home it's after 7. The trains have not been very cooperating. More bad news is somehow I hurt the side of my knee to the point where I can't walk or bend it so going to class is definitely out at this point. I still can't pinpoint where or how I injured it but I've been so busy lately it could have been doing anything. As much as it pains it I'm going to take it easy and rest to let the injury heal and if needed see a doctor.  It's so frustrating I've only been to class three days this week but somehow someway I plan on making it up. I don't know when but I will!!! This will not stop me!!
