I feel like I made the wrong choice

I’m 16 when I was 15 I started talking to this guy online he said he was 17. When we met in person I found out he was actually 22. I decided I still wanted to hang out with him. He wanted to have sex and at first I was down but then I didn’t want to. He said I already agreed so we were going to.. we did. After that I blocked him and didnt contact him again. Five weeks later I realized I was late. I tested and it came back positive. I was in shock and wasn’t sure what to do. I messaged someone I trusted to go to planned parenthood and decided it was in everyone’s best interest for me to get an abortion. It was a hard decision but I made it. Now fast forward ten months when I should have a baby and I don’t. My mom found the test because I kept it- i couldn’t just throw it away -and whenever she gets mad she throws it in my face and it would be so much easier if I had my baby. I see others with their babies and it makes me hate myself. I feel so guilty. I see all these post about women mot being able to get pregnant and i just threw mine away and it hurts
