How do I find myself after years of being everyone else?

You can become almost any voice. It is a rare and strange gift, to slip fully into character after character. And it comes with a grief few people would guess: a career spent being everyone but yourself can leave you unsure who you actually are when the mic is off. That grief is real, and naming it is not ungrateful. Losing yourself in the roles was never a mistake, it is the very thing that makes you good. But a self needs time as itself too, not only as a vessel for others. If every hour is spent being someone else, the quiet question of who you are can go unanswered for years. You are meeting that question now. That is a beginning, not a breakdown. So spend some deliberate time as no one but you. Not a character, not a client's vision, just your own voice, your own words, your own choices about a plain afternoon. Ask what you actually like, apart from any role. Journal in your own voice, or make something that is entirely yours. You have given your voice to everyone. Give a little of it back to yourself, starting this week. The self you are looking for is still there, waiting to be spoken as itself.
