Smell like onions for over a month please help

Please don’t make fun of me for this post, I’m going to be brutally honest because my mental health is declining fast because of this.

For the last month my underarms smell like VERY strong raw onion. I have a sweating problem naturally, since puberty hit I’ve suffered with profuse sweating from my armpits, groin, palms and feet. But the last month is the first time I’ve spent like a horrid raw onion.

I shower twice a day, I changed my soaps razors and deodorant. I changed my diet to clean and healthy foods, I work out three days a week. I’ve looked online and everything just says it’s from the food you eat or working out, and it’s not that for me and I’m tired of only seeing that option.

It doesn’t smell like onions when I sweat from working out or physical activity. It just smells during my normal all day everyday sweat.

Has anyone dealt with this? I drown myself in perfume before I go out, and I actually have had someone tell me I smell like onions. I don’t even leave the house and I just sit here crying.

I made an appointment with the dermatologist but it’s not for another two weeks.
