Overwhelmed

I'm sitting here at work and just contemplating all I need to do and there just seems to be no time to do all that I am needing to do or is expected of me. I feel so heavy. The load seems so hard to carry. And when I think of who I could delegate some of the responsibilities to, I realize there is no on else. My husband still out of the home and there seems to be no end in sight. The children pulling me every which way, my home is a wreck and the children can only do so much, working full time and the limits that brings along with it. It is all too much for me and I don't know what to do. I'm so busy, I'm finding it hard to have any time with the Lord, how am I to also lead my children in devotions and developing a quiet time with the Lord? It is just too much. Lord, what am I to do? Who is going to help me? How long Lord will this go on? 3 1/2 years have passed and still I am holding on by a thread. Lord help me, I'm drowning and it hurts.
