Before we dive in to some ways to help, I would invite you to join me in re-reading your email by means of the lens that I see it through. I see a young woman who begins her email with gratitude to the reader, even though many others have hurt her. Someone who has been abused all her life, but still has the drive and willingness and hope to fight for herself. Who, despite all the setbacks, still finds herself pursuing her dream and is in college — and working. So sum it up, I already see someone who is brave, resilient and courageous. Someone with passion for what they want and grit to stick with it. I see someone who, in spite of everything that has happened, still has hope in the future and believes she has the power to make things better.
I’d use the resources at college. Most have a counseling center where they offer free or very low cost therapy. Talk to them about getting some services. As a backup, I’d use a local service in your area that helps match your needs with other local counseling services: http://www.ccceg.net/. Talking to a professional now about your past and future is what will help the most.
