Hi. Im similar to you in a couple of ways I’ve just had a uni mastectomy (and recon as well) I was a size 18 and have a seven year old son but am single so don’t have the same issue with worrying about what my partner will think of me. There is this great woman on YouTube called Dee Doherty and she did an awesome video ‘what cancer is like for the partner’ it might help you to watch that. The way I personally am coping with everything is to stay relentlessly focused on what I am gaining vs what I am losing. Wishing you all the very best. x
