His eye is on the sparrow...

I know his eye is on the sparrow, but I am so full of anxiety.  We just don't make enough money to live on, Mark and I both work full time, and I have the coffee stand on Saturdays at our farmers market, but we are always so behind on everything, and always have something being threatened to be shut off, down, or taken away.  Things are so up in the air at work, everyone is retiring, getting lovely high paying new jobs, or going to travel the world.  There are only 2 of us left, every one else will be new in just a few days, I am poorly paid for a very physical job, i am exhausted when I get home, and it is that way 6 days a week!  To top it off, I just feel like my work has no lasting purpose.  I want to make a difference, and all I do is cook and clean, then do it all over again.  I want purpose, and enough money to live on.  We don't have extravagant lives, I haven't got new clothes in a year and a half, and then it was just a couple shirts, I need new shoes, mine have no tread, but we can't afford them.  I haven't bought groceries on a regular basis for months, ( I am amazed how the Lord has made our food stretch)  I sound like the children of Israel when they were in the dessert, I just want to know what to do.  What should I, we, do?
