That is what you struggle with the most? Are you kidding me?
English has no distinct personal pronoun for an "it". "I" has to be used for grammar to be attributive. There's quite literally no alternative without using passive voice for everything, which is miserable to read and creates ambiguity on if the speaker (it) did something or something happened to have been done, which then requires entire sentences to clarify.
You aren't stupid, you know what it means when it says "I". And it serves a grammatical purpose. You're getting upset at a toaster for ringing a bell to notify the toast is done. "Toasters aren't bell ringers!?"
