Struggling Single Parent Needs Help

okay so I think I just need to vent or something. i need help and lots of it I have no idea where to go for it. I am a single parent to 2 kids. S has autism, PTSD, anxiety, and sleep apnea. B has brain trauma and intestinal trauma. My family says they will help me but they gaslight and steal from me. I am unable to work because nobody will hire me because of all the appointments and I can't afford a babysitter. I was babysitting some kids at my mom's house until one day she called all the parents without warning and said I am unable to continue babysitting. Her reasoning is that she doesn't want me to anymore. She stole over $5000 I had saved to get my own place and fix my car. I have been selling my clothes and other belongings to pay for babysitters, gas, diapers, formula, food, bills, etc. My WIC will be off for a little over a month because I can't get it renewed because they cancelled my last meeting and couldn't reschedule me until September 13th. The DES office says because I rent a room from my mom and she is a blood relative I have to be 22 to get CA or NA which won't be until December. I was supposed to start babysitting and staying with a friend but they are moving so they no longer need me to babysit and we can't move in. I applied for a single parent grant to a college and got denied because you have to live on campus and we can't live on campus because I have no money to move us and we legally cannot leave the state until my kids biological father is found and arrested. I know where he is and have reported him to the cops and they aren't doing anything. I have nobody to talk to besides the people on this app. My tumors are growing so I don't know what will happen to my kids when I'm gone. most of the time it seems easier to find a good family to adopt them and to just "disappear".
