Prayers uplifted to everyone in need. God Bless you all!

I could use some positive thoughts. My job is driving me nuts...and I feel like a wuss for even letting it bother me but at the same time I know I could be doing a lot better. I work two 12 hr days and two 8 hr days. The 12s start at 6 am and the 8s start at 2pm. I can't sleep during my working days and on my days off thats all I can seem to do. I feel tired all the time even when I sleep a good 8 hrs. I caught some virus about two weeks ago and its caused me to miss shifts and even though I rest and take care of myself I still feel worn out and ill. I feel like if I bring up my concerns with the higher ups my complaints will fall on deaf ears because they feel like I should just be happy I'm getting hours at all. Never mind that its turning me into a spazz...*sigh*
