I'd tell you to practice meditation but it might be a bit too much for you at first. Learn how to skip stones on a good day and practice calmly. Your goal isn't perfection or a score. You're just there to chill and enjoy small things. If you hit a good rhythm of taking it easy and while trying to skip stones, you'll get a pretty good calm state of mind out of it. Hobbies like hiking and woodworking can also help you get a good peace of mind.
Also, learn how to be stoic. It can do you good. Real stoicism isn't about putting on a face, but remaining calm, strong, unfazed and not letting others drag you into their bs.
