Could you share?

Tbh I feel terrible now, I was raised by mom and grandma& grandpa,(it was an abusive family all the way from 2 generation behind idk how these guys survived like this). My father died long time ago I don't even remember his face(I was around 4 at that time) so the thing is I always think what would be like to have a father to be there to teach on things a mother can't, what to feels like to have someone lead a way for me, to help me build my life from his experiences, all these thoughts flood my mind recently since I've been an average student(academically) and i got some scenarios where people mocked me i deserve this, that "why aren't you studying from your losses didn't you see that your father had died" "your dad died that's a way to teach you something" "you don't got no dad whom you gonna call for" "you got no dad" "call your dad" "you don't deserve having a father" "thank God, that he is dead otherwise what wouldve happened" looked down on us, after all these things I wished I had my father being with us.😞 Idk why but I'm too sensitive to these things maybe raised by a single mom or some things but idk... Everytime I see kids having father's helping them build their life, teach life lessons, I wondered what it feels like....wished to have a role model like that.. Sometimes I feel like I was always at an disadvantage, everyone around me got somekind of headstart(comparing is the theif of joy but still).. Can you share some life lessons your dad taught you... Might be helpful right? Or leave it if you don't wanna.it's okay ☺️.
