“Depression is assur. Mitzva gedola lehiyos bsimcha tamid. Of course there are times were aloud to be sad (at a levaya or on tisha bav or something else like that) but to be sad for no reason? Thats completely assur.”
do you really think that when a person is depressed he/she will stop becouse its asur? deppression is a mental illness not something people can easily control.
