I once had the great privilege of living for a while with a lovely and formidable witchy nature woman in Maine. She had the following passage from Audre Lorde's The Cancer Journals posted on the inside of her bathroom door, and I have since followed suit. I cannot tell you what good it does for the spirit, to read this first thing every morning! But tomorrow morning, oh on this morning of mornings, I wanted others to read this too as we take to the streets to speak our collective truths; may we also  listen as allies to women of color, and may we remember, may we be bolstered by the words of those who have marched before us. 
"I was going to die, sooner or later, whether or not I had even spoken myself. My silences had not protected me. Your silences will not protect you.... What are the words you do not yet have? What are the tyrannies you swallow day by day and attempt to make your own, until you will sicken and die of them, still in silence? We have been socialized to respect fear more than our own need for language.
I began to ask each time: "What's the worst that could happen to me if I tell this truth?" Unlike women in other countries, our breaking silence is unlikely to have us jailed, "disappeared" or run off the road at night. Our speaking out will irritate some people, get us called bitchy or hypersensitive and disrupt some dinner parties. And then our speaking out will permit other women to speak, until laws are changed and lives are saved and the world is altered forever.
Next time, ask: What's the worst that will happen? Then push yourself a little further than you dare. Once you start to speak, people will yell at you. They will interrupt you, put you down and suggest it's personal. And the world won't end.
And the speaking will get easier and easier. And you will find you have fallen in love with your own vision, which you may never have realized you had. And you will lose some friends and lovers, and realize you don't miss them. And new ones will find you and cherish you. And you will still flirt and paint your nails, dress up and party, because, as I think Emma Goldman said, "If I can't dance, I don't want to be part of your revolution." And at last you'll know with surpassing certainty that only one thing is more frightening than speaking your truth. And that is not speaking."
