Extremely oily skin for the past 2 weeks... Please Help?

Okay so my face has always been oily and i get pimples sometimes but can get rid of them. I am very hygienic, vegetarian and i dont eat oily foods. But since the last 2 weeks my skins been Super oily and greasy. It's crazy... I also live in Bangladesh (south-east asia) and it's pretty humid here so that contributes to the oiliness, or causing it, whichever. How do I get rid of the oiliness? I feel so ugly :'(
