Reflections on a knee

I’m wondering how much of my current problems can be related to my knee injury.
Its injury has caused two direct effects: I can’t run anymore, and I have to do physical therapy.
Because I am doing physical therapy, there are many evenings where I came home from work, do the exercises I need to, and don’t get to dinner until after nine o’clock. I was exhausted constantly. And most importantly, I didn’t have a chance to read computer books to better myself. Would I have, if I had had the chance? We’ll never know for sure. But more knowledge may have let me keep my job.
Because I couldn’t run, there are two effects from that. First, I have one less way to deal with stress. I can’t recall the last time I had an endorphin rush. Any I have been very stressed lately. Secondly, my long sunday runs gave me a good support network. I could talk to my friends about issues over a long period and get their advice. And I could be sure they couldn’t walk out on me, because, well, they couldn’t. I trust their opinion, even if it does cause me to sign up for stupid-distance runs. I don’t have that outlet anymore.
Note: I love the Friday Feasts, but they are not a good outlet for support. There are too many people there sometimes, and I don’t like speaking about personal issues in front of a crowd. I get better support from the quieter movie nights.
