Hi everyone.  I am  was diagnosed with breast cancer in January. Had a lumpectomy in February. Also had my coil removed so my hormones are all over the place.  I had five days of high dosage of radiotherapy three weeks ago and I'm still suffering with pain and a burning sensation and still tired and not sleeping at night.   I've put weight on  due to comfort eating and feel uncomfortable in some tops due to boob still being swollen and a little lopsided I've since found out that having a coil removed can contribute to weight gain.  I know this sounds crazy. But I sometimes can't help blaming myself and wondering why me ?  Did I do something wrong ?   I would love to be able to chat with people that are going through similar issues xx
