Body Odour but I can't smell it??

i am at my breaking point. I 20F am getting kicked out of my sharehouse because apparently my room smells and the owner/roommate thinks it is due to poor hygiene.

This isn't the first time I have heard that I/my room smells, she has been telling me repeatedly for months, and other people I have lived with have said the same, on and off for over 3 years. The thing is, it is not due to poor hygiene. I shower/bath daily, sometimes twice a day, I put on deodorant three times a day and perfume every morning. I have air fresheners and odour removers in my room and bathroom. I wash my sheets/towels/linens every week, and do my clothes washing regularly. I have even gotten to the point where I have scratched dead skin off my body until I am bleeding because I am just so upset and don't know how to fix it. I am overweight (PCOS) and working to fix it, I do sweat a bit and run hot but this is why I use deodorant/antipersperant and shower more frequently

I also don't even smell what they are saying! I know theyre not lying but they think I am because I have told them I genuinely cannot smell anything like theyre are describing. I am desperate and even one roommate I lived with said that she woke up feeling like puking because of the smell. I just dont get it and I cant stop crying. please help me.
