I came home late when my child was sick
Why did you get home so late when you know that your child needed you?
I thought it was the best thing for me and didn't want to call
It's understandable that you need to work, but you shouldn't leave your child alone while they're sick. They may not be able to properly care for themselves and take whatever medication they need. Try finding a friend or family member who can be there for you during a crisis like this.
I am really busy, I can't help my daughter, so I declare it as not my business.
Your daughter is always going to be your business, especially when you are sick. You should not leave a child to fend for themselves when they are not feeling well.
