Every person has their own unique derech! A great teacher is someone that sees each childs strengths and helps them develop it for the future, as we know the pusuk ‘Al pe darko’.
If the system has not yet evolved enough to convey individualized chinuch, then no wonder people go off the derech.
So for many, as painful as this may sound, going off the derech is really a distortedly good thing, as it is a sign of one’s yearning for a more authentic experience, so no wonder so many continue the search until they eventually are able to find their unique derech that they were looking for the whole time.
(And no there is no need to give up or commit suicide on the neshama, hang in there and with Hashem’s loving help, you can build your own true connection, Amen)
