I’m terrified

I recently found out that I’m pregnant, not really planned and kind of unexpected. I’m trying my best to be excited but I’m more scared than anything. Not going to lie I don’t like other people’s children, and I have a very short temper and not much patience. I’ve always wanted my own family, but I didn’t that would be happening any time soon. Does anyone have any advice or has anyone ever felt this way before? I feel really alone right now.
