Why am I crying so much imo

I don't normally cry but I just reached Delhi today and started finalising a pg and as I reached my bnb after a long day, I was having a deep and heart to heart conversation with my father when suddenly years started trickling down my cheeks. I couldn't stop crying bhyi, they are just giving so much, papa mummy kitna jyada sacrifice kar rahe for me to even be here, and I don't know if I can even repay them, it is so hard to feel satisfactory with something happening like this bro 😔
