I have no idea what helps. I do know what does not help:
1) thinking over and over about things out of your control which hurt you
---stay away from people who only want to gossip or magnify the shittiness of your experience
---those people don't care about how you are coping, they just want to talk shit about something
---stay around people who genuinely care about your state of mind, regardless of the situation
2) looking only at the small picture, and resistance to trying to see a bigger picture
---the bigger picture won't negate your hurt or somehow belittle your feelings
---letting go of the personal sting of things is liberating, you can still acknowledge the injustice of a situation without letting it tear you down
---don't let your need for validation prolong discomfort...be open to positive attitudes...sometimes a walk helps, to look at the world around in nature, animals, or in the stars and reflect on things in a holistic fashion...it tends to belittle the current shittiness (for me anyways)
3) letting my bad mood affect my patience for innocent bystanders
---lashing out at others, or cutting them off because I don't feel like talking only makes me feel worse because then they feel bad
---I would rather they left me alone, but I can ask them for space first, then if they don't give it I might have to just run away, or put on headphones, or hide in a closet
---trying to be polite while feeling like not caring is difficult, but worth it.
4) neglecting duties
---things piling up never helps my mood and reinforces my depression
---baby steps, little by little, slowly but surely, is a nice motto. just clean one thing (like a cup) and it feels good.
---if I haven't showered, washing my face and doing my hair feels good. even changing clothes if they are clean
