I’m so confused! Am I terrible? What should I do?

Okay I know I’m the worst person in the world and I don’t deserve this but my boyfriend and planned to have a baby for a while now and I was 10000% all for it and so excited and now that I just found out I’m pregnant I feel like maybe I’m regretting it now. I feel like how am I going to do this. I know nothing about being a parent and I’ve never had parents. I’m absolutely terrified and it makes me think that maybe I made a mistake 😭 am I a terrible person?
