50+ and 12 hr shifts are killing me...anyone else?

I don't know if it's the menopause, the physical drain, the mental strain, or all of the afore mentioned items but it seems as though a 12 hour shift is getting to be too much for me, at least on med/surg!

I am so ready to go home after 8 hours I can't stand it. Nursing over the past 30 years has gotten so much more hurried, intense, organized confusion, the acuity of patients is skyrocketing along with all of the responsibilities that come with it. I worry about getting pulled to areas where I don't feel qualified. I worry about getting pulled to tech because I seriously know I'll pull something in my back, neck, shoulders or all of the above. I suffer for a week afterwards just in soreness.

I used to be able to run circles around just about everyone but now I just run in circles, or so it seems. As much as I love the work and my co-workers...I think med/surg has seen the last of me. I am so physically and mentally worn out when I get home that all I can do is go to bed. Too tired to even think about eating.

Anyone one else experiencing the same feelings? Not too old to work just too old to work the med/surg floor anymore? Does it get better after menopause? I'm on an antidepressant and a HRT but it's still wearing me down. Somebody tell me I'm not alone!!
