My mum has just been diagnosed with lung cancer , never smoked or drank all her life. We initially just believed it was an infection but the diagnosis is stage 4 and given weeks to live. She is 86 , I am 44 with 2 young boys who love her to bits. We have a good family although spread apart and my dad is a rock although this has just hit everyone so hard. I read some posts on here and although I'm thankful my mum is not younger, it doesn't hurt any less. She has short term memory problems but is otherwise so sharp. Since being in hospital she's so tired all the time and they drained so much blood off her lung it makes me feel so sick and scared for the future. I am the only medical in the family , and my wife has supported but I still feel in so much pain I can't describe it. 
mum ver close to my parents but due to having kids and different reasons I've not seen them as much as I have wanted  , like once a week and I just feel regret in not seeing her more. When I wake after finally getting to sleep it just hits me all over again. Just feel like I'm living a constant nightmare. She's such an amazing mum and always tells her how much she loves me. I'm just at a loss how to move forwards. I've always been quite strong mentally but this has just broken me. I just fear she will be in pain and I fear not having her in my life. This thought just goes round and round my head.
