Kicked Out of My House

I'm the same one who write the "17 and pregnant" post. My mom and sister took me to an abortion clinic. I got there and I freaked out. The lady there told me that they do not do procedures on people who are not 100 percent sure about their choice. So we went and talked to my family together. They were nice and lovey dovey in the office. Once we left, all hell broke loose. By the time we got home, my mom had told me to get out of the house. She said that if I want to give up all my dreams and ruin my life she didn't want to watch. I packed most of my stuff and left. I'm am currently living with the daddy-to-be!! I'm lucky because my obgyn that I had through my insurance has his own clinic with his wife and they agreed to continue seeing me (free of charge). Does anyone have any advice on what steps I should take next? This is all so scarey and it seems to be happening so fast. Is there anyone else out there in my situation? I feel so alone.
