Please help my family

I am a single mother of two boys. I just recently had my hours cut at work. Im working 3 days a week. 2 to 3 hour shifts. My commute to work is a total of 50 miles a day. I live in the mountains so we get a lot of snow. I have to get snow tires and cannot afford them. I have filled out applications for more work but have not had any calls back. I am embarrassed to even ask but really don't know what else to do. If  you can't donate please just pray or think good thoughts. My youngest Sons birthday is coming up. I am very low on food and my bills are piling up. I really need snow tires and any help would be greatly appreciated... Thank you for taking the time to read.
