我想要的到底是什么，用英语怎么说

What exactly do I want?
What do I really want?
What do I want indeed?
都行啊~

简单点儿比较好，毕竟这句话的语境是对自己的问话，自己知道啥意思就好了，不用那麽多的修饰了，直接 what do i want？

What do i want on earth? (no earth到底 究竟)

What's on earth I really want？！

What is the thing that I really want?
What do I really want?

What on earth do I wanna?
