like amonia or something, sour, no ammount of deodorant can mask it, and the smell can't be removed from clothes. When u wash the clothes you can smell it right when it leaves the washing mashine, it dissappears when it dries but the moment it gets a little moist, like water or sweat the smell is back.
I've tried baking soda, different brands of washing detergent, strong vinegar (25%) to no avail.
The smell goes away about 3 days after I go back to a diet of meat and animal fat. Comes back a bit when I drink strong coffee, so I think it's something like a stress hormone. Energy seems more stable without coffee, but coffee doesn't seem to make me depressed (as much as plant based food does).
I've started suffering from that when puberty hit, but I think depression started earlier (i can remember that colors seemed to have vanished from the world one day)
