随你和不要管我怎么说啊？？

it's up to you.是用于友善的吧,让对方决定的意思...

看LZ的意思不像是要表达友善的...所以我觉得应该用just as you like!或者Have it your way!

不要管我..Do not bother me. 也可以说,不要来烦我...

help yourself
Just leave me alone

up 2 u/ whatever; leave me alone!

suit yourself and leave me alone.

anything for you ,dont care my words.

As you like and do not manage me
