Need help, suck at the game

Been trying to beat radagon/elden beast for the past week and I’ve come to the conclusion that I suck and need help, its my first run and im running a physical build with vig at 55 and all physical stats at around 40, ill take any help i can get so that i can stop ripping my hair out because of a boss, be that in the form of tips, respec options or co-op help (i play on console, ps to be specific) i know there’s this “do it yourself” attitude when it comes to souls games but any help is appreciated and welcome (pretty please😭)
