I'm always paranoid about smelling bad?

I wash my clothes everyday, I shower everyday, I wear one of the strongest deodorants out there and put it on right after I shower, and since I shower at night, in the morning I'll wash my body again and put on more deodorant. If I smell something, I always think it's me. I was on the bus yesterday and I kinda smelled something bad, but as soon as the girl left, I couldn't smell it anymore. Or when I walk past people, I'm always concerned that they're talking about it. When I smell myself and my clothes, they just smell like my deodorant.
