Make A Picrew

Went to swim today and since it's almost spring break our coach let us take it easy. We played a game called sharks and minnows. Basically, you try to get to the other side of the pool without being tagged. The rule is you have to tag them on their head above water.
Everything was going fine until my friend started to target me, at first she would just grab my arm and head trying to drag me to the surface. Then 6 people were around me on one of the rounds and my friend grabbed my strap trying to take it off. She was about to break it so I stopped swimming. I tried to take her hand off but other people were grabbing me. She almost took my strap off to where you could see my upper body. (idk if others saw) By now I was running out of air and I quickly struggled. I got out of her grasp. I later cursed at her and told her she showed my upper body and she just laughed. (idk how I didn't just punch her in the face). And now she asking me to forgive her. should I just forgive her, find a new friend, or something else.
