Just go on
Having a baby might seem like the most difficult, terrifying, miserable thing which could ever to happen to you. You would be right because it is. But that little boy, who you do not yet know is growing inside you, is going to be the most amazing person you will ever meet. He will be kind and gentle, in a way you never knew little boys could be. You will never know the true meaning of love or sacrifice until you hold him in your arms. Hold him tighty for he will grow too big for those arms so fast.
Yes, it it will be hard and it will only get harder day by day, but it will be worth it, so worth it. That little nothing nestled in your abdomen will grow to be a something which will give a meaning to you life you never could have conceived before.
It's ok to be afraid, just go on.
