Praying as a singlemom to my 3 kids

Dear God!
I am a Single Mother of 3 children.

I pray that I can have a job to provide us with our daily expenses.

It’s very hard for me to think every day how I can pay for all my expenses that I’m only doing a part-time job which is not enough for our daily lives.

Do I have to cry every day? God, please help me.
