That video did not really include self-medicating (except as screen time can be self-medicating for boredom and tiredness); I tend to self-medicate anxiety by simple logic games (picmi, sudoku, kmines — all but the last also avoid failure) which wastes a lot of time. (Drinking water seems to be a somewhat less harmful form of self-medication; it has similar sensory benefits to eating — not as attractive as sweet, salty, fatty foods but it seems somewhat similar — and distraction but overdrinking water seems more difficult.)
* Doomscroll on your phone, reddit, whatever. Social media is not your friend.
* Self medicate. Some commercial drugs are bad enough. This includes overeating.
* Get stuck binge watching.
Try things (if you can). You never know what you happen to like.
