I have an older sibling that started to throw away his belongings even if they were expensive (Tvs, clothes, shelfs,etc) and said that it was his and not to touch his things. He threw away most of his clothes as well, and removed the buttons and other things from them. And he doesnt answer properly. If you ask him what he ate he’ll say ‘food’ thats all.Then he changed his diet to just beans rice and other grains but no meats or sugars and salt. He isolates himself and doesnt want to talk. Has anyone experienced something similar? Is this depression or something else?
