Am I a bad mum for feeling like this?

I’m almost 10 weeks pregnant but I’m really struggling at the thought of having 2 children. I don’t know why I feel like this all of a sudden. I have an almost 2 year old so I don’t know if it’s just extra hard this time cause I’m tired and cause of lockdown so life is stuck on a loop at the moment but I just cannot get my head around having a newborn and a toddler. I don’t know how I’m going to do it. We have it pretty easy at the moment, my daughter sleeps through the night, has been since she was 5 weeks old, but I know we aren’t going to get it that easy again. I know I shouldn’t be complaining and I’m so lucky to be pregnant but I’m just so scared. We were excited to grow our family when we started trying but now I just can’t shake the feeling I’m not ready. I know when the baby is born we will manage like we did the first time and I’ll love my wee family but my anxiety is pretty high just now.

Did anyone else have these feelings too? I don’t need anyone to be judgemental, just some support or advice.
