Did something so naive and weird during rush

Why would you do that.

It was because you were nervous and unprepared for recruitment, so you were awkward at all the houses.

personally I did for philanthropy but it was bc of how it effected me and therefore I strengthened the bond with the active I was talking to (only did it for them, not even a super “competitive” house. houses don’t necessarily talk to each other unless you got unlucky and it was someone with a friend group in each one. That was most likely not the cases and you were prob dropped for outside reasons, but fake crying speaks a lot on your character so the other houses could prob just tell you were not a genuine person!

The sororities do not get together and compare notes before they vote after each round. If something noteworthy happens with a pnm, members do talk to each other informally through friend groups when they go home at night. If there's something really bad about a pnm, panhellenic would be alerted, like for intentional rudeness or other very inappropriate behavior.

What you are describing is not anything to raise a red flag like that, but if you did that at one house you probably did stuff at other houses and they each drew their own conclusions. Calm down, make friends in the sororities, go through rush again in the fall, and accept that the 'less competitive ones' are also exceptional and offer great sisterhoods.
