Can leaving home save my relationship, health, and prevent fights with parents?

I am having lot of difficulty with my parents, especially father. Alhamdulillah, I try to be very dutiful to them. I treat them with great respect, serve them well and tolerate a lot of their insults. I keep them reminding of Allah and Hereafter when they violate Islamic way of life. But my great sin in their eyes is my unemployment. My mother is fine, but my father keeps nagging me, taunting me and insults me every day. On the other hand my younger brother earns a lot of money but is not so mindful towards Allah and Hereafter. He is not so polite either. But he gets very good treatment from my parents. I am 29 years old and single. I am going through a lot of torture and my mental health is deteriorating. In this situation, can I leave their home to save my health and iman and avoid quarrels? I intend to serve them again when I become financially stable. Please reply soon. I am in great agony.
