People learning Southasian languages, how's it like?

I'm a native Bengali speaker who learnt hindi + urdu later down the road, along that road I've encountered the utter lack of basic resources teaching fundamentals of any of the major indian languages, not even hindi properly

I compare this to arabic where it's as easy as googling "How to say X" and I will get 20+ videos lined up that too in dialect Meanwhile you can't even google why "Mujhe" and "Mein" are different, I really wanna know the stories of people who ended up quitting especially.
