I have a suggestion for the OP.
Get involved with the youth group at his current parish (the ones his parents want him to continue attending).
So maybe the youth group is obsessed with Matt Maher and Casting Crowns, and their idea of a great social is to have a pool party at someone’s house and walk around in swim suits that aren’t exactly Victorian.
Maybe they turn up their noses at the idea of “service project.” Maybe they wouldn’t be caught dead at a pro-life rally. Maybe they would rather sleep than study the Bible or do a group Holy Hour before Jesus in the Blessed Sacrament or pray the Rosary together.
So what? They’re your peers, the ones you will grow up with and grow old with. They’re going through their own angst in their own families.
And it’s just possible that they aren’t obsessing over current music and that they don’t like pool parties because they don’t want to get skin cancer in the sun, and maybe they are already involved with youth service projects that no one hears about because they don’t want people to praise them.
Get involved with them. Grow up with them. Learn with them. Laugh and mourn with them. Study with them.
Hopefully, there are good youth ministers or youth sponsors who have a love for working with teens and a calling from God to do this work, and you will learn much from them.
Do this for a few years until you graduate. Commit yourself to your parish youth group even if they are on a different page than you (hint–ALL of those kids think they’re on a different page than all their peers!), and you will be grateful for all that you experience in this group when you are older.
My only caution is–if your youth group is involved in something truly sinful, like selling drugs or orgies–then you could skip it. But chances are good that all of the teens are struggling with sin, just as you probably are, and believe it or not, any teens in the TLM parish are also struggling with sin. So just get involved and work with all the rest of them to become saints.
