I want to be a motivational speaker

Maybe this is far fetch but I'm getting a new passion in life. My husband killed himself because he couldn't handle his sexual assault. I am the girl who made the post wondering if he had cheated, then updated on finding out and pressing charges... Then the update on his death. I have dealt with severe depression but I am finally getting up. After therapy, antidepressants I am getting up. I want to speak out against ALL sexual assault, especially on men. But how do I start? I'm a shy person. How do I get comfortable sharing my husband's story? Where do motivational speakers start? I don't want anymore stories like mine. I want victims to be able to become survivors. I want men to not feel ashamed of their raped. I want rapist to burn.
