I am a 26 year old woman that is 5 foot 6 inches and has a 30 inch waist are you overweight?

Well, honey, let's get one thing straight - your worth is not defined by a number on a scale or a measuring tape. But to answer your question, based on your height and waist measurement, you fall within a healthy weight range. Just keep being fabulous and taking care of yourself, and forget about what society says about beauty standards.
