Gym junkie?!?!?!?! me?!?!?!?!

So I have recently rediscovered the gym. Due to 14 years with a recurrent dislocating patella I have not been able to do any sports at all, just turning a corner would dislocate my knee. I endured 3 surgeries the last being an absolute major that saw me in a wheelchair and off my feet for nearly 4 months and then on crutches for months after that. I still have significant weakness in that leg, and I can only bend it about half as much as the other one BUT it is now strong enough that gym equipment I couldn't dream of using before is now a real possibility to me. So I have joined the gym at the local aquatic centre (swimming is brilliant for my knee) and for the past couple of weeks have really really enjoyed going.

The first trip I spent 20 minutes sitting in my car trying to work up the courage to go inside, the second time it was only 10. Its not that I am scared of exercise, or even that I don't like it.. I have this weird thing about being around 'people'. Yes, I am a nurse, and before that I was a nightclub manager... people are literally my bread and butter, but as soon as it stops being a professional thing and turns into a private one I am a proper mess. I'm not talking agoraphobia, I'm not quite that bad. Anyway, I got over that eventually and now its only about 5 minutes in the car before I go inside the gym ;)

Yesterday I was unable to go to the gym, due to my work hours and it being a weekend the gym was closed by the time I got home, and you know what? I physically felt the need to go. I actually -are you sitting down?- WANTED to go. So today as soon as I was free I went straight to the gym and totally killed it!

Wait, it gets worse.... I came home and did more weight training here!

Is it weird that I am looking forward to my body aching tomorrow?
