I totally get you. You say that you've lost sight of who you are, but you haven't! Like you said, you have the passion, you have the self-love. Stuttering aside, you know how much of an amazing, capable, person you are. Now it's about the mental game of remembering that every time you speak, and trying to minimize the fear of other people's judgements based on your speech. You got this!! Also, it gets better in uni (from a freshman college girl) :\]
