This might be one of the dumber submissions on this subreddit, but I really needed to find some help. I walked out of my job at Target last year to continue school--no warning, no two weeks notice. I was fed up with where I was and I didn't fully think out the consequences. 

The ridiculous and stupid part of it is that working in the food/cafe section of the store, I was eating some of the food I had to toss out and even gave employees free cookies and such, essentially stealing from the company; stupid as it may sound, I did it because others were doing it and they've been working there for a couple or more years. The new supervisor that was recently promoted at the time didn't know how to print out the schedule, so she printed out the wrong one that had private information about the employees and put it up for us to see. Next to my name was an icon indicating some sort of warning. It was only an icon, but the symbol alone was enough to understand what it meant; the same one appeared next to another employee I know they have issues with. When it was brought to a more experienced supervisor's attention, she immediately threw the schedule away.

I was incredibly scared after seeing that and was worried what actions they'd take. At that time, I was thinking I'm working two part time jobs, have no degree, going no where in my life, and now I might have some serious consequences at work. It really made me realize how stupid I was for eating their food, much less not going to school when my friends were starting their lives after graduating with their bachelors or masters, and my confidence took a hit. I couldn't face work anymore and just left without any warning. They called me for the next week and I avoided all of them until they eventually stopped. Stupid decisions after another.

My question is, what are the possible consequences? I'm graduating this semester and didn't think back to what I did until now as I'm applying for part-time, minimum wage jobs while I finish up school. I'm afraid I might be put up on a blacklist for what I did and won't be able to find even the simplest jobs, much less a high-paying job.
<bot>: Essentially stole by eating the food at the cafe section of Target while working there. Walked out/quit with no notice. I'm afraid I'm now on a no-hire list.
