@AppleFanboy I'm an old lady, so my advice may not be useful.
Do something anonymously kind for someone else. Expect no thanks, seek none out.
And keep the secret of your kindness or generosity to yourself. It becomes a bright glowing secret that is all your own. I find it brightens up the foul dark days.
Go outside, into the sunlight or the starlight. Breathe in the air. Focus on it. This moment is yours, only yours. To keep for yourself.
Best wishes.
