My dad has had threes types of cancer

mouth, throat, and stomach cancer. For the past two years I didn't know, I'm 15 now. My dad kept it a secret from me and so did my mum when I finally found out I didnt think about it as I thought it wasn't that bad but now it's hitting me, he's dying in the, unresponsive and can't move, the three types of cancer he first got were treated, but sadly he had to go bad into hospital and have another scan. This time It was lung cancer, on Christmas Day the doctors said he would die, he's still he but still unable, he's slowly slipping away I wish there was something that would keep him alive, I would give my live to day my dad but it's to late, im going to loose him, and I'm such a daddy's girl I would always rely on my dad but I can't, I can't even hear him say I love you anymore, I can't watch him die
