I dont know what to do?

I live at home. I get that. I wanted to put back money so within 3-4 years afford a car then house I can pay off.

I've struggled with jobs and my current one I am a substitute. My check varies from $180-480.

My dad never had an issue with me staying and knows I save. My mom suddenly flipped. I never did anything to upset her? I cook, clean, buy her groceries, drive and other stuff she needs.

I understand i am an adult living here but now I have anxiety and worried I'll never get a car of my own.

I'm actually worried. :S
