I know you had an ectopic pregnancy recently, that could be contributing to your generalized sense of unhappiness. THat is pretty traumatic.
I know sometimes I feel some of the same things you do. I just get so sick of it all. I think in general we all do some days.
But if these feelings persisit, I would mention it to your doctor.
Hang in there, get some rest and take care.
I know it sucks not getting a bonus this year. But remember, it's not about the gifts either.
