Hi Daisy,
I hope you don't mind me replying to your post - I don't check in often now, but your first message struck a link for me and I just wanted to say that I'm so so sorry to hear about your Dad, I know first hand how difficult this is for you and your Family at this time (as do all members on here)
I know how it feels to be a daughter, and your Dad to be your best friend, to find out they have cancer and it be advanced is terrifying and overwhelming all at the same time - but you really have come to (in my opinion) the best place.
There are amazing people here that will always be here to help and guide you, honestly they are totally brilliant, 24/7, I found this site to be my 'get out of jail card' Here I could say what I needed and the advice I gained in return to help myself, my Mum, My Family & most importantly my Dad was brilliant. When I felt scared or alone (although I have a big loving family around me) this is where I found myself late at night.
Never be afraid for sharing how you feel, as you will get support and that is so so important.
The Doctors and Macmillan staff really are amazing, and the treatments available will really help your Dad. I know it won't be an easy journey but I wish you, your family and most importantly your Dad a pain free, long road head and it really can be a long long Road ahead :)
