why do i stink so bad? i mean i sit in the house all day in the a/c set at 67 degrees,?

i don't eat or drink very much to be honest i don't do much of any thing,(very depressed since my wife pasted last month) so my hygine at the moment is lacking to say the least at the moment, but i used to work as a carpenter in the heat all day and never stunk this bad, so does depresstion cause the body to smell worse?

i shower in the eveings at the same time i have tried 5 differt soaps, shampoos, deodreants, an aftershaves, to no avail. i smell worst then some homeless people, and i have a doctors appointment for next week

well off to shower and hopefully you might have some answers for me.
