Single mother of two who’s fallen on really hard times

I am a single mother of two who has fallen on really hard times in a very short span of time. I have always prided myself on making sure my children don’t know or couldn’t see that we were struggling, but with things falling apart so rapidly, it’s been hard to hide the fact that I am struggling to manage our basic needs. I don’t have any money to buy basic essentials such as toiletries or groceries. I’m forced to send my kids to school a lot of times with little to no snacks, and hope that they like the school lunch that day to actually eat it, because I don’t have the money to afford extras. When my bank account would be very low or negative, I would use my credit cards just so that we wouldn’t go hungry, but now that I’ve maxed them out handling those things, I don’t have a backup, so now I am going without most times just so that they can have something small to eat at night. I have asked my apartment complex to come down on the rent due to ongoing issues at the hands of the apartment, just so that my children and I don’t have to move like we normally do yearly. There are things that are pending due to be shut off. I am behind on my rent, uilities, cable, car note, and credit card bills. I am flooded with constant emails and text messages about late payments affecting my credit score and putting me in a bad position, but if I don’t have it, there’s nothing I can do. I cannot lose my car because that is our only means of transportation to get them to and from school and doctor’s appointments and get myself to work. Even with all that’s going on , my kids are very grateful for the little that they do have, so that makes me feel that I am doing something right in regards to them. They are still small enough to look at life through their innocent glasses, but big enough at the same time to see me struggle and sympathize and try to offer me with solutions to help at their young age. I don’t have family that is close and people that I do know that are close are in their own predicament, so no one is able to extend a helpful hand. I need way more help than the maximum amount limits listed. Any help would be greatly appreciated, especially because it will then allow me to get back to a state of being present for my children.
