B.M.
Big hugs to you. We went through this about 2 years ago. My husband had a nice job with a nice salary and then out of the blue he got laid off. It took about 10 months before he found a job that would support us. In the meantime he applied at Target, Best Buy, and various other companies doing whatever he could to bring in a paycheck. Groceries were our main concern, so we found a program through our church called AngelFood Ministries. I looked it up for your city and state and here is the number that you would call for more information: ###-###-####. You can also go to their website https://www.angelfoodministries.com/
Essentially you pay $20 or $30 and you get a months supply of food. Meats, frozen dinners, vegetables, fruits, eggs, milk, cheese, oatmeal, cereal. It helped us out a tremendous amount. We would still have to spend maybe another $20 a month getting bread and other items, but it cut our grocery bill a great deal! Because he was out of work and we had an infant (our daughter was 7 months at the time) I went ahead and applied for WIC. This enabled us to get tuna, milk, cheese, cereal, and some baby food items. I stayed on WIC for about 2 months, and then after he got a job making more than $15 they said we didn't qualify anymore. But I would definitely look into it!
I know it's hard, but PLEASE try not to stress out. If you are part of a church then I would also contact their prayer ministry and outreach ministry so that they can know what is going on with your family. I know our church has always been a saving grace for us in our times of need. Whether it's people praying for you or bringing you meals or helping with your kids, I would encourage you to find a church home if you are not already in one.
I am praying for you. I have been there and my heart goes out to you.
