scared & freaking out

So first baby, right? & just about everything is scary. I'm scared I won't be a decent mom. I'm scared I won't be able to breastfeed. I'm scared about labor. Im scared my mother in law will judge every choice I make. I'm scared of anything & everything that can happen. I talked to my SO & he just doesn't get it. He seems so okay with all the changes that are going to happen & here I am 35 & 4 days, freaking out about everything.
