Suggestions on what to do with my life

So I am a 15 years old boy and no longer believe in the church. I am not public about this. I continue to go to church even though every bit of it makes me cringe.

So far my plan is to play along for a few more years, go to college, and weasel my way out of a mission and live my life not going to church.

If anyone has been in my situation and gives advice, that would be helpful.
