Cass., Prayers for your Dad and {{{Hugs}}} for you both - no wonder your scared.
Can I just add - go and see him as soon as you can sweetheart - don't put it off. We always think there's lots of time and sometimes - time runs out. I'm not trying to frighten you just make you aware that in this world awful things happen. Go and see your Dad, even if it's only to say 'I Love You Dad - your special - and thank you for all you ever did for me'. Please.

Lynne
