You could have Bell's Palsey. It sometimes affects people under a lot of stress, and then sometimes it can affect people that tend to be nervous or anxious by nature. You could have had a mini-stroke, which is possible if you take diet pills or caffeine pills that make the heart race, or if you have a family history of stroke or if you have high blood pressure that has gone undiagnosed. I would definitely see a doctor, you're too young to just let this ride. Best wishes!
