How do you guys sleep at night?

Chest pains. Stomach hurts. So many negative thoughts rushing in my mind. Trauma, regrets and heartbreaks flooding my mind every minute. I try to distract them with games and watching anime etc. but it's getting worse.

It's the worst when I finally turn off the lights after being exhausted but my mind can't keep quiet and I feel so fucking sad. I really think I developed insomnia at this point.

Edit: Thank you for all the comments no matter how small. I really appreciate it.
