I have an interesting stench?

I smell bad and i have no idea why? I shower regularly, I am a hygienic person, but for some strange reason i smell bad? I suspect my anus is the problem. I have been eating bad for a month, but now I am starting to eat completely healthy. I just quit smoking and drinking alcohol. I talked to a doctor and he stated i need to see a dermatologist, but those options aren't available because I am in another country and I don't know the language. I'm becoming depressed, and finals are coming up, and basically my life is a mess right now..I am avoiding going outside at all, and this includes attending classes.
