I regret having a baby
Now that you realize that, are you keeping the baby?
Yes, this mess is now my problem even though I don't want it.
I'm sorry you feel that way. It does show great strength of character that you're willing to remain a parent even though you realize you didn't want to be one. You will be a good parent, I think!
You are right. I am trying to be a good parent but it's horrible.
Taking care of a child can be difficult. Don't be afraid to reach out to family and friends if you need help. That way you don't feel overcome by the burden of being a parent.
