Body Odor - Desperate for a solution

Hello. I'm new here. This body odor really affects my whole life. I was 16 when this strangely appeared. I'm very a hygienic person and I'm not obese or something. I was bullied, insulted, disgusted, teased, and underestimated by people around me. They look at me as if I like the odor to stay in my body. I stopped going to school and I don't go out of the house anymore. I isolate myself from everything and I don't function that well. I stayed in my comfort zone. I think I'm developing anxiety and depression already. It depresses me more because I want to finish college and be successful but I can't even go out of the house. I used to be a cheerful and fun to talk to but I'm not anymore because I panic and I feel awkward in public places because of this. *Insert lots of my bad experiences and struggles* Now, I'm 18 and it still the same. I'm trying to figure out what causes my body odor. I do have armpit body odor and I just encountered new body odor from my genitals or maybe from my legs?? I get confused because sometimes, people tell me I have armpit odor, some tell me I smell like a poop. When I smell my clothes, it doesn't smell like an armpit odor. I also smell gas from air??? I'm confused and suicidal. I'm still young. I want to do the things I need and I like to do but I can't. I can't accept this, I want to find a cure. I badly want one. (Sorry for my bad grammar)
