Read once somewhere that both heaven and hell surround us and it's all about what we choose to pay attention to.

When nothing works, go for delusions (only if you're stable enough to not have them break apart the nature of your reality too much).

Also, go travel; be it on the other side of the city in a new coffee shop, in a new town for their town's day or sth, or in a new state/country/continent, travel somehow manages to shuffle the internals in one's brain enough to reboot to a different baseline; good trick for when current internal state is too meah.
