Definition: This phrase is commonly used when you want to express that you do not recognize something.

Background: Two 8th graders spoke to FOX 5 NY's Jodi Goldberg about a state-required Earth and Space Science exam they took which they believed was unfair. One of them, Samuel Tae exclaimed: "My Heart Dropped, am I supposed to know this?" The other student, Andy Ryoo, told Goldberg, "The test felt like a reading comprehension test, one of the questions was about toll payments - weather wasn't covered, which is a huge topic, and we spent months on it."
"Yo my bro, this morning, I saw the new guy and my heart dropped, I was like, am I supposed to know this guy?"
"Yo bro, this test was lowkey kinda buns tho, like my heart dropped, am I supposed to know this?"

I know! Right?!

It's pretty clear what the speaker is trying to convey: "I agree."

I agree with most of the other definitions, which provide details on the subtle context/audience-dependent connotations. I agree that phrase is annoying, used by speakers who use other annoying phrases like "my bad."

I would like to add to what has been said by providing side-by-side analogs; that is, alternative, equivalent but more acceptable expressions.
