Help Explain Something

So i was playing valorant with my cousin today and tpmidway the game someonw said do you think pesi is better than coke i said yes and my cousin said "i dont fucking know" and i said "hes not asking you hes asking me" in a very rude way which i regereted because she got embarrased and told me shes not gonna buy me boba anymore and shes not gonna play wih me anymore and to me not to go in her party again i said sorry half heartedly then the party suddenky got quiet theni checked, she left the party and unfriended me....

tbh ive never rlly apologized my life and im a bit akward to apologize and be sweet to people around

So idk how to aproach her as shes probably gonna unfriend me on genshin and discord so i have little to no time and is looking for a way to approach her but being me its very hard to do that

So i need your help

I need to aproach her and apologize to her as shes my only friend but i just cant get to do that so i am asking you to help me apologize to her

Its completely all my fault and i should have done that disrestpectful thing so i have nothing to defend my self with
