peanutpie, mine was open surgery also and I too have pretty impressive scarring! Well, I flip between feeling that it is impressive, and a 'badge of honour', to hating it, hating what my body has become! My scar is also very itchy. Is yours itchy? Are you looking after it well, massaging it (you can use anything, gentle body lotion or oils) to help stop lumps and bumps forming?
Re the energy, it will take as long as it takes. Don't underestimate the toll that the cancer, and the op has taken on you, and be gentle with yourself. I probably took it a bit too fast, wanted to be 'back to normal' asap; in hindsight this was a mistake.
And the shock? Mine was absolutely worst in the time between finding 'a lump' and having the op. I think my time lag was 7 weeks, and during this time I literally could not think of anything else. I was useless at work, useless at home, and very, very snappy. I just wanted that thing out of me. I really could barely function. So am frankly amazed that you managed so much during your 6 weeks!!
I think rather than shock, my issue (post op, with full diagnosis), was one of acceptance. The 'why me?'. I also did not want to tell many people about it, and still hate talking about it. I really hated that it dominated my life so much, and really resented it, and what it had done to me, resented all the appointments. Basically, I was very, very angry!
So now, I am nearly 3 yrs post-diagnosis, and 6 months since my treatment ended, and for the first time actually, I don't think of it everyday - MaryAnn, your post just made me realise this - thanks! That's something to celebrate, right?
