Should i go to this concert alone?

So the summer slaughter tour is coming up. :D I'm a 13 year old girl. I have been to a death metal concert before with only 1 friend. I unfortunately don't have anyone to go to this one with. I was thinking of going alone. At the last concert I didnt really stay with my friend cause she didnt want to mosh with me. So I mosh, headbang, and all that and I'm pretty strong. It would be ok to go alone right? If I go with someone I usually end up leaving them and going to the front or moshing, haha. So good idea or not?
