Strong Body odor

Im a 18 year old senior in my last year of high school. Ive always had a problem where I felt like I had to fart all the time at school and was able to manage it buy holding my farts in until the end of the day but recently it's gotten alot worse my butt feels sweaty during class and I have felt really sweaty I shower 3 times a day use powders but I still feel sweaty when I'm at home I really don't feel it but at school's it's horrible evetytime I get up or move I hear people sniffing and whispering it stinks. I've whent to the doctor and all they said was you can't stop sweating or farting. I even keep deodorant and calogne in my pocket at school but it still doesn't work my family tells me it's all in my head but they don't go to school with me and ive literally had people come up to me and ask if I take a shower I've thought about dropping out but it's my last year of high school I just want to know if anyone who are maybe experiencing something similar has any solutions or ways of making it better Tweet
