I (18F) got mad at my friend (18F) this week for being so insanely annoying. She just won't stop crying, and when I told her to shut up everyone made me out to be the bad guy!

She was seeing this guy (27M) and was super attached to him. I thought he was creepy but it's whatever. When he ghosted her, she lost it. She was already pretty stupid before this, but now she comes to school every day and won't stop crying. She brings flowers and picks the petals off and plays that "he loves me he loves me not" game and makes a huge mess with them.

I find it really annoying. She was doing it yesterday at lunch and I told her to stop crying and littering the table. She started crying harder and our other friend told me to stop being mean. I argued that she needs the tough love if she ever wants to function normally (we go to an alternative school and she's just really ditzy and delayed). Our friend fought back and said I was "too mean" to her and she doesn't deserve it. They left the table and didn't come back today. AITA?
