Sometimes you just have to do something in the full knowledge that it may hurt. I say may hurt because most of the time it doesn't, but if you accept that you might have to bail and take a tumble you'll spend more time enjoying the good stuff than worrying about any potential bad stuff.

As you personal purveyor of quack psychology I suggest a course of longboard therapy. he hee 

My great introspect/realization happened after a near death experience, I don`t recomend that. I suffered a long time keeping my secret, It took four hours of freezing to death before my head cleared and I saw what was true,actually a very similar experince to some tribe`s vision quests.It`s  best not to wait till your over thirty ,broke down in a snow storm without a jacket,cellphone or a hope ,to decide .  If I had more support, in my teens , I d probably not be so f`d up now, do whats right for you, what your soul says, not your brain, your brain will get you everytime.  Plus at your age , if you try and fail, or try and bail, you`ve got lots of time to try again.
