Caring after child with no help..

It's only 1 wk since my CL left and I been taking care of my LO. Never been so exhausted and emotional in my life especially when she didn't nap much, drinks round the clock and very clingy. I can't get any rest at all and wonder if I shd just send to IFC earlier. Originally plan to send after my maternity but I don't think I can survive that long!
