I feel drunk and high mixed with mentally unstable.(I am)

I just got back from a concert, and I am crying. We got floor seats, so we were on the area in front of the stage. But there were a bunch of drunk guys. And I was one of the two children there(the other girl was standing with me), so the drunk guys made this HUGE mosh pit right behind me and my mum. And they start bumping into us and stuff. So my mum and I get separated. But a bunch of mums, older sisters, and dads helped me and the girl. They got us to the VERY front, like, the rail. This is basically as far as you can go in a concert. So I was right in front of my idol. And in between one of the songs, she pointed at ME, and said my outfit was cute and was something she’d wear if she were younger. But at the end, one of the guitarists was handing out picks and stuff, and the guy standing next to me, who was a dad, told him to give one to me. And, the lead singer, my idol, was giving actual roses out to the like first and second row, and she looked at me, called security over, handed them a rose, and pointed to me to give one to me!! Im so happy, Im crying!
