Dude, this was so good to read. Thanks for that, you summed it all up, good to know I'm not the only one.
I'll still sum up my situation though just in case it illuminates anything.
In high school, skiing defined my life, I obsessed over every aspect and repped every skiing-related thing I could. I didn't really associate with the people in my high school, instead looking forward to going to the mountain as much as possible and riding with people I met up there (some through NS). I'd spend a month looking forward to a ski film premiere, buy every ski movie I could afford, and spend all my time on NS saturating myself with the skiing culture. I was a skier through and through, and though I wasn't that good in the park I felt like I had a place that fit. I could answer any identity-related question with something to do with skiing, and I was proud of being that kid who wears bright clothes that are too tall.
Then as high school wrapped up, it just started fading away a bit as other aspects of life came into play. What I'm gonna do as a job, girl issues, education, etc. Went to university and got less than 20 days of riding. Didn't ride my backyard setup once last summer.
At first this falling out with skiing was so scary. Since skiing was who I was, I felt like I was essentially losing my identity. I tried to progress to define myself as a skier, then as a result stopped having as much fun while riding. This just made me less stoked, feel less identified, and into a bit of depression.
I started finding other things that I liked a lot over the past year (like making music), and now that I can identify myself with that I can accept that I'm not JUST a skier, and the pressure is gone. I love skiing again, and though I don't find myself daydreaming about it all jittery every day, I enjoy my time on the hills more than almost anything. Nothing to prove, just amazing times with amazing people, in amazing locations. I don't think that love will ever go away, even if it isn't always the first thing on my mind.
