It's been two weeks since I finished radiotherapy after going through lumpectomy in February.I was doing ok up until a couple of days ago and now I feel tired and very emotinal . I am struggling to sleep and everyone tells me I look dreadful. I have just started taking leterozole too. Wasn't expecting to feel so emotional as I thought I had moved past that stage . I am getting sharp pains in my breast and tenderness around wound area. Is all of this normal ?
