Someone help me please.

I wrote this loooooooooooooooooooooong love letter in witch I confess my love to my crush. And now I just put it in the mailbox and I want it back. As a first, that person ain't gonna love me back the way I want it. Secondly, I think I am not ready for a no. Of course, it's allowed to say no, but seeing my emotional status right now, I don't think it will be taken too well. And last, there's so many grammar and spelling mistakes in it, not to mention the differences between what I wanted to write and what I actually wrote, it's not perfect and I want it to be perfect. If I am going to do this, it has to be perfect.
