I feel so scrambled

I feel very scrambled.  I'm being switched to the daytime shift.  I had been working the overnight shift.  So I've been trying to get my body to sleep at night and stay awake during the day.  It isn't fun.  I end up feeling like I'm not good enough to get through school and work at the same time.  I feel like I can't handle it mentally.  At the same time I need medical care and I don't have health insurance, so I can't afford it.  At times I am so mentally wiped out that it becomes physical.  I need to do laundry and I can't push myself to go to the laundromat to do it.  Life is a problem.  I feel like I can't do it sometimes.  A day or two ago, I laid my head down right next to where my cat, Chloe, was sleeping.  She got up and licked my head.  She has never done that before.  If it wasn't for her, I wouldn't be around.  I pray to God that I will always stay but I have moments of weakness.  Please pray for me.  Sometimes I really need it.  God bless you all.
