Apart from "generally trying to stay healthy", I have trained myself to go through this process if I "Feel bad and don't know why": Did you eat well? Sleep well? Exercise properly? Have a meaningful conversation today? Articulate and share an emotion? Listen to someone you care about? Do something intrinsically satisfying today? Enjoy yourself today? If you can't answer yes to all of the above (add your own prompts), then blame that rather than Random Problem X and come back when you can answer yes and if you still feel bad and don't know why then tell someone, possibly a professional. Usually once I can answer yes to the above I'm fine.
