My family says I have been acting like a bitch and I am so offended by their statements.
You're upset about your family's attitude toward you?
Yes, because my father always makes fun of my decisions.
I can definitely see why you would be annoyed if you think your family has a negative attitude toward you, but you should try to be respectful toward them. If you feel upset by how they treat you, have a conversation with them and explain how you're feeling. They will probably be open to trying to change how they act.
I feel they will never change.
You should try having a calm conversation about how disrespected they are making you feel.
