I'm just tried 😴 (venting)

For some reason Collin has stopped sleeping through the night, wakes up 2-3 wanting his sippy cup or to play for 10 minutes before he falls back asleep. He wants to shower with me, get dressed with me, go potty with me. As of last week he won't nap. The only help I have is about an hour before I go to work when my dad comes to let me get ready. The factory job I'm in has been working 7 days a week since December and although I'm grateful for the extra income it's really beginning to take it's toll. Also second shift is hard because I go in at 2:45, we often don't wake up until 9 or 10 so mornings are often rushed to do chores or go grocery shopping. The last few days I've just been drained of energy and not wanting to do anything. Is this normal for single mothers? Would it be wrong if I found a house maid to come once every couple weeks to help with cleaning? I need help
