Confused

I suffer with depression but found a week ago I am 16 weeks pregnant. I had to stop my medication due to the risk. Everyone seems so happy. I have been told I can’t have kids since I was 15. I had a miscarriage. I feel uncomfortable and when everyone ask me how I feel about the pregnancy I am like yeah I am happy. Truth is I’m am petrified of pregnancy. I’m scared. All I want to do is cry. I keep having nightmares that as soon as it’s born I will reject it and that scares me more. Please tell me I am not the only one to feel scared! I don’t want any negativity... I know this is probably just my depression... I’m so confused
