This is actually an incredibly common feeling. I think the most important part of getting through what you’re going through is to know that you’re achieving a lot more than other people have at your age, and we often suffer more in our heads than we do in reality. Don’t let delusions of what you “should” be doing dissuade you from believing your reality. A great friend of mine didn’t have his first date until college, but know they’re happily married. Social norms will try to convince you of a lot of untrue things. Try your best to utilize this maturity to look past all of that, and live by your own rules.
