Why I smell bad after sitting down for 5 mins or more

When it was the last month of school for me until summer, I started seeing that after I sat down in the chairs and i felt like a skunk. One day in one of my classes, I sat down and people could smell swamp like stink when they were near me. I felt so embarrassed of myself. I started loosing friends because of this and my anxiety is catching on to me. I Wash my clothes, take a shower and even were 100% cotton underwear.  They're not tight.I use powder as well and still smells. Please help me I dont want to keep happening to me.

I am very sorry to hear this!!  That is probably really upsetting and I hope it gets worked out.  Sounds like you do all you can hygiene wise which is great.  So, you are female? That helps me know about possible answers.  Also, what is your diet like?
