I think you're beautiful and you're not only taking up space, you are sharing the space. Only apologize if you are absolutely wrong. Live with NO regrets. Dare to be fabulous because the people who care will celebrate you and the people who don't care don't matter.
I love "Dare to be fabulous" and the idea of viewing our interactions as celebrations of each other. You are so right, we do coexist in the spaces we inhabit and the relationships we create.
