Typo in Update Letter

This forum made possible through the generous support of SDN members, donors, and sponsors. Thank you.
I just submitted an application update to like 7 schools, and noticed a glaring typo in the first sentence (my->by). Can someone cure my neuroses?
This is not a "glaring" typo unless it changed the sentence to one that would be socially inappropriate. Feel free to give further context.
 
"I'm wrestling with some insecurity issues in my life but thank you all for playing with me."
 
True, they might not even look at it. I had a big typo in my actual personal statement even though I proofread it like 100 times. Whoops
