Help Me Help My Child!

my husband literally walked out on us, I am getting by w paying my bills. But can't afford anything extra. My son is a great student and young man and i hate to see him suffer. I've NEVER had to ask for help and if it wasn't for my son I wouldn't. Its his senior year and that's such an important one. I need help with school supplies(including laptop, cause husband took when he left), school clothes and shoes and senior pictures. Every single dollar will help and be so greatly appreciated. Thank you so much for any help given, but understand if none is given cause my problems shouldn't have to be somebody else's. God bless even taking the time to u this.
