Oh dear, @Locksley - your story brought a tear to my eyes :(
Please don't see yourself hideously deformed! xx You are battle-scarred - that's all! And the surgery has gotten rid of the bad bit! Wear your scars with pride!
I hope you've got over the nausea & are feeling better now & able to eat - and also less pain. Make sure you take your pain meds every 4hrs (or whatever they tell you) and don't let the pain sneak back by NOT taking the meds!
Make haste slowly .... do what you can - and ask for help with things you can't. Your family & friends would be only too pleased to be able to help you. It helps THEM, to help YOU! xx
take care & all the best for your results & ongoing treatment
