body odor

Hi! I am 19 years old. I am suffering from Body Odor even WITHOUT sweating because when I go to public place early in the morning (meaning it is not hot) I notice that people starts to cover their noses or simply face away from me so that they cannot be able to smell me. My family and I cannot smell it. I shower regularly and I try to use Deodorant, baking soda, lemon, and alum but unfortunately nothing work. I will appreciate any response, please help me. It is really embarrassing. My house is only my comfort zone and public places are like hell to me.
