Oh @Sazbe you poor love, you are really in the weeds.
Someone here said they were once told by a medico that there was no clinical purpose for pain. Can you get some stronger painkillers? There really is no point in suffering if you don't have to. I had quite a lot of pain with my WLE but it subsided quite quickly, in a couple of days, apart from movement related pain.
General anaesthetics can make you feel low, as can lying there with nothing to distract you from the big bogeyman. Have you got something you can listen to on an iPod etc? A podcast, talking book or some meditation?
As for your husband, I'd like to suggest that you put aside your expectations, as clearly they are not going to be met. My mother said that for a long time in her marriage to my father, she hoped that he'd give her thoughtful, meaningful and lovely birthday and Christmas presents. She'd drop pointed hints, but it rarely worked. Early on in my marriage I was making a similar complaint about my darling husband, and she told me I'd save a lot of heartache if I stopped expecting and just bought the gift myself. She was right! So apart from the odd moment of wistfulness for a grand romantic gesture, I've let go of it.
I think the definition of madness being doing the same thing repeatedly but expecting a different outcome could apply here! Perhaps letting go of your expectations of your husband will save you both some considerable angst and woe.
You are clearly very considerate of your husband's grief and pain. Perhaps through this BC experience you could designate someone else to be your 'person'. A relation, or a best friend? Maybe even two people. Sometimes you find that it's not your closest mates who step up in times of crisis, but the circle beyond the inner one, or a colleague. People surprise you, and with a few exceptions, always want to help.
As for your uneven boobs, well the rogue one will settle a bit and time will tell whether you really go on to care about the uneven nature of them. Lots of women decide they don't, and you can always see a plastic surgeon about augmentation or reduction to match if you do. Care that is. Give it time.
Breathe lovely. Be kind to yourself. And remember you're never alone here. The Whale of Doom has got you at the moment. You'll feel better in the morning. Big (but gentle!) hug, K xox
