Dear Joe,
I have read about your situation.It is common for everyone to have arguments or even quarrels with friends.So take it easy,and find a way out.(表示安慰和鼓励)
You may follow my suggestions.First,try to find out who did wrong and caused the arguments.If it is you,be brave enough to say sorry to your friend.And if it is your friend,you shouldn't be too hard on him or her either.【高分句型一】Instead,try to take it easy and be kind.Second,give yourself and your friend some time to calm down,as it is not necessary to deal with the arguments immediately.【高分句型二】(叙述自己的建议)
Good luck and best wishes for you!(表达祝愿)
Yours,
