I'm ashamed to even ask this?

I was hoping someone would have some advice or insight as to how I can go about with this balance. I am currently working as a nurse, which I love, but I also have a long history of depression and GAD (which I am working with my doctor on). I really do love my job, but the way Im feeling is really starting to interfer. Please understand, I don't want to be some medicaid mooch who sits on the couch all day, but Im looking for info regarding some sort of health insurance if I were to drop down to per diem status at work, which would make me non-union and, therefor, ineligible for the company plan. I am BY NO MEANS saying I wouldn't work entirely,I just think the freedom to choose my schedule around managing my symptoms might be beneficial. I currently work 4 days a week, which is the lowest one may go at our hospital and still be unionized. Per diem is, I believe, 2 days a month but I am more than willing to pick up up shifts as I can tolerate. Has anyone been in a similar situation or have any advice? I am so ashamed to even ask this ;(
