Physical Therapy butt kicking.

Man. I just got my butt kicked. Well, not really. I just got back from physical therapy though. On the way to PT I'm always stoked like "This is gonna be awesome! I'm gonna move around and feel so good!" and then once I'm there it's like "Wait I still can't move. This hurts so bad. I want to cry. Why did I think this would be fun?" It happens every time. I know I need to commit to PT to get better, but it doesn't feel like I'm getting better, it just hurts. I can't wait until I finally have my range of motion back and I can actually work out and start looking forward to snowboarding again.
On a good note, my therapist measured my knee bending at 85°, which is up 20° from when I saw her 5 days ago. Hopefully this keeps going up until I reach full bending and I don't get stuck at any point.
