Between a rock and a hard place

So, during this past Xmas, my family had no money. I was going through a very tough time at home (being at odds with my mom). I had resorted to extremes out of desperation and fear, and stole cans of food from my place of work at the time so I could at least eat that day due to being too afraid to eat at home. I didn't bring any lunches because I wanted to preserve the food we had for my family. I had never done anything like this before and will never again. I've been filled with regret and resentment ever since, and nothing can justify what I've done. My parents don't know the real story because I had lied to them saying I had forgotten to pay for 5 cans of food during the Xmas season. After the holidays, I had a plan to be able to save money to pay it all back. My manager and someone from corporate judged that I owed the store $85 for my crimes. Then, just yesterday, I get a call from the people who were handling my restitution. They said out of nowhere that I also owe $250 for fines and damages. Just before this, my bank account got fraudulent charges for $120, and I already barely had even that much. I don't even have $50 to my name right now. My dad is talking to folks to go to court or something about this based on the version I told him and my mom, and I never needed it to blow up like this. I just wanted to find ways to scrape together the money to pay it back. I'm terrified on what they will think if I tell the truth. He says the store is bullying me for cash. I'm terrified and in a real shithole. I haven't been able to land a job since I lost the job I had in the very beginning of February. Everyone has rejected me or said they were fully staffed. I'm already limited on my jobs due to where I live and that I have a severe case of high functioning autism. I'm terrified to tell them the truth. I'm so scared. I've never taken dishonestly before, and can't forgive myself for it. I'm a pretty honest person, so this feels terrible and wrong to lie about to my own parents. I'm so lost. I've been trying to keep my chin up, but I'm crumbling mentally. I can't even eat or exercise like I usually do. I'm terrified and confined to my bedroom from utter fear. If I don't say anything, I can't imagine what this will spiral into. But if I say something, what else will this spiral into? I'm fucked either way. Might as well enjoy my calm before the absolute hurricane that's fixing to happen.
