How to find other ways to relax to replace my becoming harmful one?

Hi, I'm 17f and I have a bit of an issue. I tend to go to my local park to just hang out on the swing set and swing for sometimes up to well over two hours, I'll just sit there and sing while listening to music and daydreaming whole scenarios and scenes in my head that match the music. It helps me relax and it's a great thing that helps me regulate myself.

But there's an issue that's becoming literally painfully obvious, everytime I go on the swings my legs rub raw against it. Leaving me with very painful wounds on my hips and back/inner parts of my thighs, and it's really becoming an issue because it hurts and they're leaving horrible scars.

But I love the swings and I love just being on them and swinging back and forth while listening to music and daydreaming, but I don't like being hurt afterwards because of it.

So any tips on things that maybe could replace my swinging but would still give me that good relaxing feeling and allow me to daydream?
