what would you tell your daughter? or future daughte

I'm 21, i was with my boyfriend for a year and it got physical lastnight and we've parted ways. I am heartbroken. i know its for the best but im so hurt my chest physically hurts. The emotional side of me is in shambles lol but the rational side is like you're going to look back and laugh about how stuck u were on him. i just need some encouraging words and advice. How do i get over this break up? what are some tips? and what would you all tell your daughters or daughters you may have in the future?
