I'm scared, what do I do? (I know it's the wrong category)?

I am so scared; I don’t know what to do?!? It was horrible; one second my friend and I were coming out of my house, and the next, shots were being heard from every direction. We went back in out of horror, luckily I had a gun for protection, and about 6 shots. I went back outside; my friend had remained inside while calling for help. I was cautious and wasn’t sure what to do. I stepped casually outside while tightly holding to my weapon. Suddenly my leg burst out in pain! I fell in agony and red liquid was everywhere. I aimed my weapon at the attacker and randomly fired. I was in a daze, and couldn’t see much, but I had heard a loud scream, and assumed it was a hit. My friend had also heard it, and went outside after making the call. He saw me on the ground and rushed for medical supplies. I had hit my head going down, and had fallen unconscious according to my friend. He had taken care of my head which had a gash in it, but my leg was bleeding. I don’t know if the attacker had gone away, and I don’t know what he attacked me for. My question- how do I tend paintball welts
