Single mom in need of help please

I'm a single mother of two young children ages 6 and 8. My 6 yr old was diagnosed with autism and my 8 yr old has severe ADHD. I am a fulltime nursing student. I am honestly financially struggling bad. I cant pay my bills nor keep gas in my car to get back and forth to nursing school. I have ask my school if they have any programs that help people like me and unfortunately they don't. I have tried applying for cash assistance but I am not eligible because I do not work right nor due to my children's schools being closed. I am so stressed. I cry every night because I am so stressed trying to figure out how I'm going to pay this and get this for that. I am not the type of person to ask for help but I have no idea what else to do. I have no one else to ask. I am begging you please help me. Anything helps even a $1. My car is out of gas right now and I have to be at school tomorrow and I don't know how I'm going to get there. Please. Thank you so much.
