if you're a human adult you physically need to eat actual vegetables, read real books, work, exercise, be outdoors, have sex, and have other real adult humans to talk to all on at LEAST a weekly basis or else you go will literally go completely insane and the problem is too many people choose to skip all those basic needs on purpose
"I'm depressed and always tired and my body is in mysterious pain all the time for no reason" yeah you've spent a whole month isolated except for talking to online people and coworkers and eating convenience store snacks for half your meals with 0 physical activity like that isn't passive self harm. of course your body doesn't like that, it's exhausting
you lost me at sex I eat my vitamins but get 0 hoes am I gonna die
Exchange that for "have a positive physical contact with another human being, preferably mutual" and you're golden. Cuddles, hugs, lying next to each other, massage, it's all good, doesn't have to be sexual. Also plot twist: not all naked activities have to be sexual, you can just chill with no pants. Pants are optional.
All these things OP listed can manifest in many forms. Find one that works for you, whether it's audiobooks, going on walks or munching baby carrots. You got this â™ˇ
