Annoyed at skate group at my skatepark any advice

So I’m at the skatepark with my friend and I’m going down the pump track and my friend comes right behind me to the point where we got off the pump track at the same time, even tho didn’t get hurt it got me nervous because how close he was so I asked him “yo next time don’t come so close to me it got me nervous” he just laughed and said “my fault” til randomly this guy that I thought I was cool with said “why do you even skate if you can’t even go down with somebody behind you” I was about to say something rude back until I just said “can u just stop talking pls” this dude got really petty and started going at me I forget what he said because I wasn’t listening but he was mad. Later me and my friend are hanging out in this bowl nobody was using so we just used it as place to chill for a little bit, then this dude from before comes over to us and asks us why we were talking bad about him, I wasn’t I was talking to my friend about a guy I didn’t like from my school. So I try to explain, no I wasn’t talking about you and then he says “okay man stop lying” and then he walks away and me and my friend leave the bowl and he walks back over with 4 of his friends, pressing us for no reason saying we took their vape, I have never vaped in my life and idk why they came up with that. Also some other information is me and my friend are 14and these people are 19/20 so I tell them if they actually put they’re hands on me I will tell somebody and probably call the cops and they just laugh, I just find this annoying because this similar situation happened awhile ago, then I tried to get the know them and I started to be friends with them and now they are being rude and annoying to me and my friend again I just wanna go to skate and hang with friends we weren’t loud and we didn’t bother anybody so idk what to do. Any advice?
