feeling like a let down

I just got back from the doctor since I've been having pain in my abdomen and my daughter wasn't moving much only for my doctor to tell me she thinks I might have a kidney stone and she wantings me out of work until further notice which means my husband and I are back to one income and I feel like somehow I have failed him and our daughter it's not fair that he has to do it all by himself and I can just stay home but my doctor says my anxiety is too high and that since my work won't let me have a break and I'm on my feet 8 hours straight she wants me out of work
