I'm new to this site but wanted to share that my dad was diagnosed 12 months ago with lung cancer. It has spread to his liver. He has been having chemo & remained jolly as best he can. However yesterday he got the news that it is advancing. He has always been a very active outdoors person but is spending more time indoors. Over the past month he seems to be getting more down with his mood. 
My dad has not always been the best dad. He came in & out of my life as a child. He was 18 when he had me. He remarried & had other children and I was forgotten about. It wasn't until I was in my mid 20's that he contacted me again and we have since built a good relationship. I have never asked about the past & just moved on with him in my life. 
It is very obvious he is closer to his other children. After all her bought them all up. He missed chunks of my life. I find it really hard that he has stage 4 cancer. I feel sad for all the years he wasn't there in my life. Although my sisters, step mum & dad are now a big part of my life I still feel jealousy if they get together & do things without me. I'm sad I never got the relationship with dad that they did. I am supporting my dad the best I can. I tell him I love him but he never says it back. 
I don't no how long he has left and feel I don't have enough memories. My sisters talk about how he is the best dad anyone could ask for and it hurts. I no this should not be about me and it is about my dad. I'll support him until the end and will also support my half sisters.

sorry to waffle on. This is the first time I have done this.

thank you
