Someone please share with me the greatest parts about being a mom

I’ve been so down lately and feeling like I’m not ready for this baby and have been considering termination. I don’t want to but I have fallen into a deep depression and can’t decide which choice will be better for me and my husband. I have always wanted a baby so I don’t understand why I’m not excited about it anymore. I’m so scared of how our lives will completely change and I’m afraid of struggling financially. This baby was not planned so it’s very scary for me. I don’t know who to talk to bc I’m afraid of being judged
