Is it normal to resent your child under these circumstances?

I never wanted another child because I knew I didn’t like kids enough to keep having them but I ended up pregnant by mistake. I kept the baby and it’s been nothing but a fucking nightmare. I miss my old life and on top of this the child has autism and/or adhd which makes raising this child much harder and draining. I wish I never had this child. Worst decision I’ve ever made in my life.
