At the age of 44, I can say that I've had quite similar social struggles in the past from time to time. I've mostly gotten over them by realizing that I am what I think about, for better or worse. If you can vision yourself being a certain way and keep visioning it in your mind over a period of time and not dismiss it, and believe it is truly possible/reality, you will inevitably become that person, again for better or worse. My main help with these things is my relationship with God/Jesus.
