Someone once asked...

“Tonight me and my really good friend we're practically brothers we do everything together and we've been friends for years now and never gotten into a genuine fight. We were supposed to go trick or treating together (I will do trick or treating until I am not allowed to anymore I do NOT care. Until someone turns me away I will keep getting free candy) and they kept texting me being like "bro hurry up I don't have much time tonight" and I got really mad and just told them to go without me over text and that they should just go have fun while I stay home and they texted me saying I ruined their night and that they'd been looking forward to this for months now and I sent them like an essay on how sorry I was and I know it won't do much cause I was an asshole and now I don't know what to do”

You have apologised and taken the blow. Don’t ruin it by begging it will have the opposite effect. Wait patiently and with sympathy. I’m sure they will forgive you in time. :)
