Feeling down

Devon
I don't think I've got postpartum depression but I've started to feel down about having to do daily physio on my baby :( she's one month old and has something wrong with her neck that prevents im her turning it to one side!! I now have to do physio on her atleast 4 times a day where I hold her shoulder down and force her head as far as I can to the side she can't turn to. She screams and her face goes purple, I've only been doing it for 2days and already I'm feeling down about it. I know it needs to be done but I hate making her cry :(
