Creative isn't just traditional art and drawing, there's no way you've tried everything creative and everything makes you feel shame after. Poetry, writing, painting miniatures, origami, flower decorating, 3d modeling, programing, crocheting, macrame, pixel art, bead art, stained glass, mozaic, and so much more. I know "don't worry about the end result" doesn't lessen the feeling of shame, but instead focus on something super simple and approachable for a beginner to accomplish in whatever creative endeavor you engage in. Start small, build from there.
