Hey mate, sorry to hear about your mum, my auntie got diagnosed with cancer on her kidneyr 5 weeks ago now, they said that one kidney is deffinatly dead so it will need to be removed, and if they hurry up they can save half of the other one,
we was gutted, when she went for her opperation, things turned for the worst, the cancer had spread, so you guessed it both ahd to come out, now she needs to go to the hospital every 3-5 days to get all the ***** pumped out of her bodym because she has no kidneys, she is only in her 30's,
its hard mate, trust me, tears one day smiles the next, things will never be the same, but that doesn't mean they wont be better, it took me 2 weeks before i went back out with my mates etc, when i did i still didn't feal right, she was happier then me and shes the one who had the opp, i suppose you sorta get used to it, but think of it this way, if there happy, you should be happy
Once again i send my condolences
