I think I stink all the time
Why do you think you stink? Did someone tell you something?
It is because of me. I don't trust people who says it's not me but the people around me
Well, if you personally think you stink all the time, do something about it! Unless you're homeless or impoverished, it's simple.
So should I start putting on more deodorant or perfume?
Practice basic hygienic principles every day and you'll never think you stink again. Take a shower, brush your teeth, put on deodorant and wash your sheets and clothes regularly. It just takes a little time and effort.
