Financial help needed to pay for weekly expenses

Please I need financial help. My microwave blew up and I needed a new one which I’m paying off. I’m on limited amount of money and sometimes need about $100+ a week on after pays and Zip not to mention my automatic payments I have weekly. I am behind in paying Chrisco. I need it for my autistic son to have a Christmas. I try and trust God, but it is a struggle. Thanks be to God.
