Was I stupid to quit my fast food job with no backup plan?

I've worked at mcdonalds for 3 months. Its fast paced, stressfull, customers are asshats, higher ups constantly bitching about times. I put in my two weeks yesterday. I'm scared because I don't have a job lined up, but releaved, because the end is in sight.
