When I watch pro play, I don't enjoy the game anymore -- anyone else?

It's strange, because when I first started playing the game I didn't even know there was LoL eSports. I really enjoyed playing, I still didn't like losing, but I never flamed, and I had way more comebacks.

It took me a while to realize that when I watch proplay I actually play worse and I flame more, even though I feel like I understand the game better. I'm going to stop watching proplay again, which makes me sad because I really enjoy watching it, so that I can enjoy actually playing, which is more important to me. League is really the only way I relax right now, but when I feel terrible after playing and losing a game it actually affects my day to day mood.

I know there are a bunch of you out there that watch and play and don't have any problems, but does anyone experience what I'm talking about? I'm wondering whether it's because I watch a LOT of proplay: I watch game replays on my lunchbreaks and in the evenings when I eat dinner.

Thoughts?
