How to deal with telling parents

Sydney
I'm 19. Just told my mom I'm pregnant. She didn't know what to say at all, but she thinks I should get an abortion. Everyone does. I want to keep it, because I'm against abortion and adoption would be extremely hard for me. I feel like I have the most unsupportive group of people around me right now and I just want to leave and never come back. I need help and they don't even know what to tell me. (My mom was 20 as well when she had my oldest sister) I thought I would at least have her to confide in. I'm locked in my room, crying my eyes out and I want nothing to do with them at this point. I know I'm young but I'm the most scared person in this situation and I'm getting nothing back from anyone. I hate this.
