What do you do after some guys try to jump you and your friends in a Safeway?

Okay, so we were at the store between theatre performances, like fifteen of us, around ten of which were in seventh grade. Everything is okay until our curtain guy comes up to me and points out four guys and tells me that they want to beat him up.

Apparently, the leader hit him with a chair and insulted his family during summer school and after the curtain guy beat him in the subsequent fight, he's been trying to hurt the curtain guy every time they see each other.

The guys were following curtain guy around the Safeway and even tapped one of the seventh graders on the shoulder to ask if they knew curtain guy. Curtain said that the leader of the group was known to carry a knife on him.

I was panicking, but I quickly let two of the other older kids know what was happening and we wrangled all the younger ones out the door. Sure enough, the thugs are waiting at the other entrance for curtain guy.

We set the kids walking at a very fast pace and we just didn't acknowledge the guys behind us. We were almost to the school when I looked back and realized that the boys were following us. They weren't going to catch us unless they ran, but I decided to play it safe. Me and the other older kids told everyone to run the rest of the way to school. The younger kids were confused, but thankfully they listened to us and we all ran into the building. I had some of the girls take the kids into the theater to calm them down, then we decided to go to the teacher because the guys were still outside.

She handled everything and said she would let the principal know what happened.

In the mean time, I had to explain to the kids what happened. They were all pretty shook up from suddenly being told that we needed to run, but I told them exactly what happened. They were pretty shocked and one of them started to cry. My friend took her off to the side and comforted her, and I stayed and talked the other younger ones through what happened and thanked them for doing what we asked. They were still a bit surprised, but talking about it as a group seemed to help. We did another show and moved on.

I've just gotten home and I'm kind of just realizing what happened. It was all adrenaline while it was happening because I needed to get the kids and curtain guy out of that situation ASAP. Then I was composed because I needed to help the younger ones process their emotions. But now I'm getting to address my own feelings. I don't get in situations like this much. Our school doesn't have a lot of fights because there is no tolerance for it and we have the coolest sixty year old ex marine security guard who can break a scuffle up in seconds. On top of that, I'm just not a fighting person. I don't get mixed up with the wrong crowds, and when I have to interact with them, I'm nice and friendly and they normally either ignore me or like me. My friends aren't fighters (except for the one guy who is a ninja), we're nerds and band geeks and scene kids and theater kids. And we get on well with people.

I'm kind of at a loss of what to do. I definitely don't want to run into the guys again. Obviously, their issue was with the curtain guy, but I was pretty obviously the one leading the group. I don't exactly feel safe going to that store anymore. What should I do? Is their any way I can process what happened? It's all very overwhelming...
