I've gone through similar experiences, and at least for me its been a mix of learning how to turn off my internal inhibitions towards positive spontaneous actions my unconscious self wants to do. This could be things like wriggling or dancing while listening to music I feel while alone. Going off on random nature walks and indulging my thirst to explore randomly. Roll around in the grass because I can. Hit blocks of ice with a hammer because why not. Swagger around like you're in a cowboy movie and try to win a quick-draw against yourself in the mirror. Dip dried squid in chunky peanut butter because you wonder if the two flavors will mix or not. And so on and so forth.

Of course I've gone through almost a decade of trying to improve my mindset from being a nihilistic doomer that couldn't enjoy anything except atrocious shock jockey edgy "humor" to someone that gets blown away by the beauty of the rising sun on a daily bases and giggles like a child having a fit at terrible dad jokes like "don't forget to eat your vegetables, peas!" Or talking about China's monorail transit systems and saying "I bet this subject would make a great One-liner!" It also helps that my material conditions have changed to a more positive environment and I'm around generally more fun and positive people I can learn from and joke with.

Just remember you can't learn it over night, but with steady commitment of trying a bit at a time will help you develop yourself as a person in the direction you may desire.
