In September last year, my dad was diagnosed with lung cancer. In the space of 5 months it's gone from manageable to terminal. Chemotherapy and radiotherapy didn't work and he ended up losing the use of one lung due to radiotherapy  

It's now the point where his home carers and nurses think he could leave us any day now. I'm not prepared for it and I never will be and I have no idea what to do. I'm still a teenager, I'm only 18, and I've been a daddy's girl my whole life 

Seeing him in pain had been horrible and to the point where I didn't think I'd be able to go and see him anymore as he just isn't the same person. But I need to somehow prepare myself for the inevitable. If anyone could help, that would be great.
