Agree with what others have said here. Stoicism, meditation, diet, and exercise all help. If you're ultimately unhappy with your work, though, your life may require deeper change. When in doubt, make art (broad definition) about your feelings. Draw, write, or compose music to get your feelings into a tangible format you can look at. If you decide to go this route, let your art be shitty. Just let it be shitty and make it anyway. I've made some super crappy beats in Garageband that nobody else will ever hear, but they helped me process through feelings.
