Hi firstly I am very sorry to read you post about your lovely dad. My dad had prostate cancer, though he is still having health difficulties I am so relieved he is now cancer free.  I can understand your pain and fear about loosing your dad I had 18 months and it is truly horrible.  Your feelings are your own, there is no right and wrong way of coping, you just do what feels right at that moment in time.  I like you wanted to hide my fears from dad, I was worried that sharing my fears would burden him more..my dad is also not a talker with regards to his illness and we always had to give him time to process what was happening to him and then he would talk and tell us what was going to happen next...I have to be honest that was really hard,  give yourself time to process what is happening,  when you feel ready you can come together to talk,laugh,cry and be angry about your dads diagnosis all these emotions are normal 

In answer to texting,it's a lovely way of saying I'm thinking of you both, I love you but I want to give you some time together, you can always add but phone if you need me x. I don't doubt for a second your mum and dad know how much you love them.  With regards to meditation if you have access to a hospice or a Macmillan nurse they would point you in the right direction.  My lovely best friend had terminal cancer, she enjoyed the holistic therapy on offer at our hospice and we were able to access some of the treatments too.  I don't recommend the hangover option !! Been there got the T shirt  you only feel worse.   keep posting on here, there is always a friendly ear willing to listen.

take care, thinking of you x
