Welcome @Flossy. I was diagnosed in December last year at 54 after a routine screen. I was just ticking the boxes getting my health checks and had no idea there was anything wrong. I was in total shock to get the call back and then to find out it was positive. I had lobular carcinoma with node involvement (also ER & PR +, HER - ) and ended up with a mastectomy and dissection. I then went on to 6 months of chemo - AC-T. I won't lie - it wasn't fun but it was do-able. It does affect different people in different ways. Some go on with the practicalities of life with few side effects, some are get ill at times through it, most fall somewhere in the middle. I'm on to my radiation programme now as well as hormone therapy. I know that I'm giving it all I can to stop it coming back and that's all I can do.
Try to relax and enjoy your birthday trip. Let the waves and sunshine take your worries away for a little while and capture a happy place in your memories to go to when things get you down. (And don't forget to tell @socoda when your birthday is so she can put it on her calendar!)
