Recently I was lucky enough to get a rather large and ongoing assignment for a company. As fortunate as that is, the income I received lowered my assistance rather harshly and abruptly. As my goal is to get completely off assistance, I needed to get some help feeding the kids while the transition took place.
I called the local food pantry with the Salvation Army to see if they could help. I was able to pick up food donated by others and the local grocery stores. Fortunately my kids love bread so all the bread really helped. I also received some grocery money to buy some fresh items.
I believe this and other services are available for others in most areas. Call your local economic services department and ask if there is one around.
One thing I would like to do when I do get caught up is once a week go to an elderly person's house who is having a hard time making ends meet or getting help and make dinner for them with groceries I have purchased. Since I have a family of my own to take care of I can't do this every day, but helping out and making a new friend would be very nice.
