So sorry to hear both you and Karla are going through this with your Dads. I'm exactly the same, I'm 27 I'm engaged to my partner of 8 years we have a beautiful little boy whose almost 3 years old, we own our own home so we have a lot to be thankful for however a big dark cloud hovers over me constantly and that is the thought of losing my dad who was diagnosed 15 months ago with stage 4 incurable bowel cancer which has spread to his lungs and liver. Knowing that he will die one day from this dreadful cancer terrifies me, watching him deteoriate, struggle, knowing what he and my mum are going through daily together hurts like hell. Knowing he may never walk me down the aisle, meet another child of mine, see his little grandson grow up to remember him properly. I know how you both feel. It's like a prolonged suffering, that doesn't go away, that doesn't get any better...it leaves you feeling scared, worried, uncertain of the future. I understand and I'm here to chat to anyone of you. 

Big hugs x
