garbage/ onion underarm odor

Hello everyone, I am suffering from a garbage/onion underarm smell. I am very depressed about this, and no deodorant works for me. I have been homeless, raped, robbed, my life has been horrible but I have finally found a good job. I am very scared that I will get fired because of my underarm odor, I shower twice a day, i use hibiclens and anti-fungals under my armpits but the smell still comes everyday. When i try to wash the smell off I am unable to. I started my job last year and I was very overworked, I was stressed out daily and i gained about 30 pounds.I also ate a lot because people would tell me that I was " too skinny" . I am hoping that this Body Odor is a simple fix, i am going to try to only eat fruits for 3 weeks and hopefully the b.o. will be gone. has anyone cured their garbage/ onion underarm smell? thank you in advance
