Once you get to a shelter, they will help you with both legal help and therapy. You need to heal your Post Traumatic Stress Disorder from the past, so you will be able to recognize whether a boyfriend loves you or not. This one doesn't love you, he just loves having power over you. Please get help immediately. Talking to me won't do you much good, because I'm so far away. Call a woman's hotline, or a shelter now. "How to Keep Yourself Out of a Violent Relationship" will give you some information that will help. You might also find It Ends With You will help you work through your PTSD from the past.
Listen, I can forgive and understand someone not having a computer (you can use labs at school) or a Smartphone (they're not for everyone). But 21-year-old Ana Steele not having a f*cking email address? Seriously? No one graduates or even enters college without an email address. Your college will give you one if you don't have one already. And if you don't have one already, you're either Amish, elderly, or don't exist.
