Broke 20 year old.

I’m currently 20 years old, I make around $800/mo and my bills are currently $360 not including gas or food. I currently have around $2,000 in debt. My cheap truck is on its last leg. I work 2 miles from home. I basically live paycheck to paycheck it feels like and I’m not disciplining myself enough to save or attack my debt. I also need at home cheap meal ideas. Any tips would be appreciated! I live with my aunt currently and I’m starting college in January.
