People don't understand why I'm anti-family.
Is there a reason why you don't want a family?
Well, my parents always wanted me to be the successful son. And that isn't what I want.
You can live however you want, as it's your life ad not your parents. You don't have to agree with them all the time. If having a family is not what you want then that's fine and people should respect that.
They must respect my choice and they aren't supporting me.
Your viewpoint on having a family is valid and it's your personal choice. I'm sorry that people are not respecting and supporting you, but their ideas shouldn't influence your beliefs and how you feel.
