AITA for telling my parents they need to learn to live without me?

A 17 year old Redditor feels overwhelmed and overburdened by the responsibilities placed on him by his parents. As the oldest of 10 children, he has been treated like a third adult in the house for as long as he can remember. From cleaning and babysitting to driving siblings around and making decisions, his role has been more of a parent than a typical teenager.
With his 18th birthday approaching, he plans to move out and start his own life. However, his parents are panicking at the thought of losing their support. When he tells them they need to learn to manage without him, they accuse him of abandoning the family.
