I've been feeling kind depressed lately. I have to go back to work on Monday

On top of that I've been suffereing with some shoulder pain for quite some time. I finally saw the doctor and ahve learned that it's a torn rotator cuff. I see the doc for follow up on Friday to see if I'll be having surgery or what. May need an MRI first. I'm in extreme pain all the time. Everything i NEED to do involves both arms. I have to carry Hunter, and putting him in and out of the crib takes some INTENSE breathing, and a lot of crying afterwards. I'm worried I'm going to be told to stop doing these things and I know DH can't handle it alone. Hunter is up literally all night long and it takes both DH and I just to make it through the night.
Being only 4ft 11 I can't reach much without stretching so that in itself is a lot of work. And now I'm stressed cause Hunter's party is supposed to be next Saturday and I have NOTHING planned. I only have this weekend left to get work clothes, and that leaves only evenings to plan a party. Well, it's only family, but it's his 1st birthday!
