breaking down in public

I’m afraid I fucked up again.
I was out partying the other day and everything was going really well. I was having fun with a friend I made in the bus (I was on an trip in Italy with school) I genuinely was having fun which is rare as it is.
Than all of a sudden she mentions that someone she knew someone who committed suicide that day almost a year ago. I tried to comfort her but just ended up breaking down myself and needing her comfort. aka I sat there crying for about an hour on her shoulder for everybody to see.

Obviously I told her why I broke down. I don’t think anyone else really knows about it because she didn’t tell anyone and I haven’t had people come and “cheer me up”

Should I just ignore the situation? Should I actually use this opportunity to open up about this whole thing? Quite frankly I’m just afraid to do anything 🙁
