Thank you mummylin. I was TT before.
I wasn't always in contact with my Dad because my parents split when I was young and my Dad had problems with alcohol so I didn't always know where he was. Then he got ill and gave up the alcohol and wanted to make contact with me. I didn't make contact for years not because I was angry, I wasn't at all angry because I knew he loved me. I was shy, a grown woman too shy to make contact with her own dad how pathetic. 
Then I finally made contact and the first time I saw him I wanted to ask him to move closer to us but I didn't and we only saw each other sporadically because we lived quite far apart. I should have seen him more, I could have seen him more but I let the day to day stuff get in the way.
Then he was diagnosed with cancer just over a month before he died and I saw him a lot but still not as much as I would have liked. I realised how alike we were and how much I had missed out on.
I don't know why it has only just hit me. I think it all happened so quickly. There was so much to sort out that it felt surreal.
I have a lovely photo of him that his niece gave me at the funeral. I met my Dad's side of the family for the first time at his funeral and they are lovely and I wish I knew them before.
My Dad's death has made me realise that I have lived my whole life wrong and I want to start again. I can't turn the clock back.
