Drs note??

So here's the deal.. I used to work 6-2 then because other people wanted schedule change I now have to work 2-10 2/3 days out of the week... Usually 2. I can't stand working 2-10! I don't see my family.... Especially Sunday's! That's family day and the day I get ready for the week... I have always worked 6-2 even at other jobs... And now that I have to work 2-10 it has me hating my job, I have gotten anxiety from it.. I have never gotten anxiety. Not to mention I'm a caregiver and med-aid who's on their feet for 8 hours a day! And I walk about 5 miles a day... I don't mind working Sunday's.. It's the fact that my boss is catering to others who either don't have a family or don't have school.. I've asked her not to schedule me 2-10 on Sunday's and she laughs at the fact I get anxiety. Do you think a Drs note would do justice?
