You point to your own upbringing which you managed to overcome
I am not the only one. In a different thread I advised someone to talk to FRUM B.Y. type girls and yeshiva boys and see if their lives are all a bed of roses. I advise you to do the same (I’m not sure they’ll just open up just like that) but you might be surprised there are not only those who left the fold, but frum teens too have have been abused or hurt or are in pain for various reason and have overcome or are overcoming their challenges in life.
In addition some OTD teens have led a pretty okay life. Of course, nobody has every single wish they want in life, but it was average. Then they go nitpicking on every little detail that wasn’t too their liking.
It’s all the direction one wants to take.
