Dilemma

I have decided that I am totally peeved off at work, well not exactly with the place I work but with all the hassle I get from my department.So I am thinking change, do I totally change jobs or do I go to a different department. The bad thing is if I move departments I will have to take a pay cut but there would be a lot less stress.
There are some hours I can do on our jewelery/fashions but, do I go for an earlier start 7.30-12.30/1pm or do I go for 12-6pm shift.I would need to do extra hours to make up my money loss, I shall have to wait and see.I love my job now it's just that it is pretty stressful and I could just do without it.
Wouldn't it just be wonderful if I could just win the lottery and then all my problems would be over.......
