hero vs, burden

I found out today that my dad has been paying my aunt's rent. He also has helped her fix her car. He's been getting really stressed out about money. I feel like I'm just adding to all his stress by still living here. He had talked to my brother (who also still lives here) and I about getting financially situated so we can move out and my dad can get a new job. He's unhappy with his job (which he works sometimes 13 hours a day), he has two grown kids living at home, and he has to be financially responsible for his older sister. I feel terrible. Terrible like I have failed him just like everyone else has. He has to take care of everyone. He always has to come and save the day. When can I become a hero instead of a burden?
