Feeling like i'm almost done with the game

I loved Mh World and Iceborne but i have to do Alatreon and Safi'Jiva, i feel like it’s just impossible, i have to get an elemental weapon for Alatreon and break his Horn but it has to be an specific element or idk, or it will one shot you, and Safi, even with 4 players, we didn’t do much damages and i died 2 time, someone said "what broooo"and i felt like it was my fault, i wanted to uninstall the game, i just feel it’s impossible to continue and have fun, i don’t know what to do, i don’t think i have as much patience as before for difficult game as this or souls...
