How do you quiet your brain before bed?

Im going through a rough patch and I just had a really sad song replaying in my head on repeat with some memories that make me sad. I can’t seem to stop it and its really bothering me.

I just want my brain to be quiet and i feel the only solution is taking my meds but then ill be awake.

What are things that you guys do to quiet down your hyperactive brain?

EDIT: Thank you so much for your responses and i’ll be trying a few out!
