yes I need to change jobs, but how, what can replace that incom

I work 10 - 11 hour days in front of computer screens under florescent lights neck craned up. It is effecting my health. Just do something else, ok I'm not replacing an income to buy shoes and purses. I pay the mortgage, the car insurance, health insurance, house insurance, car payment (which isn't much is a 2003) I buy the food.

No I can't get up and walk around 5-10 minutes an hour...throughout the day, the once or twice to make tea people notice your wasting time.

No I don't get breaks, ever, it don't happen in this field.

No I don't get a lunch break to go work out and get active.

No I can't do yoga in my cube.

I am a robot, I work steady 10 STRAIGHT hours, on a computer, in a bad chair providing my own keyboard tray. It's my field, and YES it's horrible on the body. My legs feel heavy I'm often numb, tingling in arms shoulders it wears over into the hours I'm not sitting in this chair. I try I do to sit correctly but it's hard to keep conscience of that while we need this done done done done.

What I need is an income from my talents, a REAL income, one that can pay for the same things this one does without the constraints of being chained to a desk hour after endless hour. I've tried to find something else, I keep trying.
