What should I do

Good morning ladies ! I need to vent to you ladies! I can't take it anymore! I need you guys honest opinion. Roughly about 4 months ago. Me my best friend and her sister. Got into a terrible argument. We all said stuff to each other. Now it's been four months and I won't lie I miss them so much! I consider them my sisters the once I never had. I know we harmed each other. But I'm the type of girl who hates being mad or angry at people for such a long time. Should I talk to them and asked them for forgiveness and move on. Or leave it as is?
