I don't feel anything for my family
Why don't you feel anything for your family?
Because I was abused when I was a kid.
It's okay not to feel for those who wronged you. You should seek professional help so you can confront the issues you have with them.
Why should I do that?
It seems you have some unresolved issues with your family. I think it's perfectly OK not to care for toxic people in your life. You're just going to need some help.
