Bills are behind, no car, and 2 year old son needs diapers

Husband w, No where,

I am a 24 year old mother who has two wonderful children ages 2 and 3. My husband recently walked out on our family and took the only car that we had causing me to lose my job because I couldn't afford a babysitter. I have no family to help me out in this time of need. I can barely even afford to scrap up enough change to get my 2 year old son diapers. I have seeked help with local agencies but have gotten no help. Any help would greatly be appciated in my time of need.
