I don’t know if it is generally good advice, but this personally saved me from spiraling immediately after a traumatic event. When I started, it felt like a thin line between mild depression and utter insanity:

Sleep and wake up at the exact same time every single day, with no exception (obviously as much as you can).
For the first hour then, do the same sequence of actions (eg. drink coffee, listen to podcast, stretch, …).

Waking extremely early is best for me as I end up alone in quiet, but I assume this would work even for a night owl.
It is like keeping an anchor in your daily life, when everything else is confusion.

Not much, if you don’t like humous

ITT people mentioning bipolar disorder but I would suggest a strong onset of Premenstrual Syndrome (PMS).
My only question to you is, when did your menstruations start this month? You don’t have to reply to this.
But look up whether they started the day you were sad, or one day/two days prior.
If it was the case, it is very likely PMS.
Keep a calendar of your cycles and you will know.
Causes of PMS may be one or many, like birth control, undiagnosed depression, a stressful time, etc. etc.
Edit: typo

I never clicked on your posts because I thought they were literally meh random screenshots and nothing more.
Damn was I wrong. You are building the Lemmy museum of videogames.
Thank you!!!
