- Listening to upbeat, energetic music and avoiding depressing music, which tends to make me feel worse
- Walking outside on a clear, sunny day
- Eating my favorite food
- Playing a good game to get my mind off whatever it is that I'm obsessing about
- If I am able to concentrate, reading something by a favorite author, listening to a good podcast, or watching a non-depressing movie (most of my favorite movies are, sadly, pretty depressing, so those tend not to help)
- Doing exercise
- Getting enough sleep, but not too much
- Improving my diet and supplementing to overcome nutritional deficits (this and regular exercise are long-term fixes, and have helped my mood and energy level tremendously)
- Talking to a good friend, or maybe calling a crisis hotline (though the results vary greatly depending on who you wind up talking to)
- Journaling (I've been using a voice recorder for years, and this makes journaling much easier, more natural and faster for me than writing... just talking things through, even effectively just to myself, often helps a lot)
- Talking to a good therapist. They can sometimes provide insights and offer good advice that I otherwise would not have thought of.
- Looking at the stars on a deeply dark night sky, and thinking about how small and insignificant my self, my problems, and everything else on this earth really are
- Reading stories of people who've survived ordeals and overcome tremendous adversity. This again helps me put my own relatively trivial problems in perspective.
- Then, as Nietzsche said, "The thought of suicide is a great consolation: by means of it one gets through many a dark night."
- Finally, I try to remind myself that I've been through this many times before and I always eventually feel better. Time heals all wounds.
