I usually take a very hot soak in the tub for about 45 minutes to an hour. I darken the room, have only candles lit, I put lavendar oil or rose attar in the water, and then I keep adding hot and cold, and I soak until it is a question as to whether or not I will be too woozy to get out. By the time I get out I am as red as a lobster, woozy, and all I can do is flop onto my towel on the bed and let the fan run on me to cool me off.

It's an exercise in deep relaxation, and because of the heat and the wooziness your concentration is on immediate sensations and preventing yourself from getting heat stroke.

I would talk it out. I would say to myself that it is just one moment in a long day. It is only temporary. I would do something to unwind. Hike. Walk. Yoga. Talk to a friend. Play music loudly. Sing. Drink hot milk before bed. Count my blessings. Bad times don't last.

Just know that tomorrow is another day with a clean slate :) and today is in the past now

I don't. It takes time to overcome the bad thing

I just process my thoughts and try to calm down...

Melatonin

Usually once I turn onto my left side I fall asleep in less than a minute. Not much prevents me from falling asleep.

go to the gym, speak with someone uplifting, watch something uplifting about relevant situation..youtube's full of great stuff

Go outside and look up, can't stay uptight when the stars are putting on a beautiful show.

Bit of exercise, get the frustration out.
Hot bath and warm milk drink to relax.
Soft music.
Sleep.

I don’t forget about it if it bothered me it won’t umbother me

I suggest you drink heavily.

Do what you can correct, then the rest tomorrow...

Sleep with music playing

Smoke weed
