what has happened to me?

Dear FutureMe, Although I think this website is probably a joke, I am willing to give it a try. Happy Birthday (since i'm going to send this on my...ours? birthday)! I'm sure by the time I'm (we're) gonna get this I/We will have no idea what the heck this is. I hope our future is bright and I/we accomplish many things. I have no clue what will become of us by the time we're 30, if that's even the right year because i am pretty bad at math. i tried to start with correct puncuation but i'm really not into that, well....i'm sure you'd know. its really weird to be talking to myself. but future self, make me proud.
