I am 26 years old and my dad who is 50 years has terminal brain cancer. Since surgery July 2015 he hasn't been the same. Hallucinating, talking to passed on relatives and overall acting like he is 5 years old. He is going downhill and i am so scared to loose him but the way he is now isn't living. He is currently in a nursing home can't talk, swallow properly or generally do anything. I feel like I am grieving my dad but I still see him all of the time. I don't know how much longer he has and my mum has gone away on a cruise and is not contactable and has told me if he passes to not tell her. I don't know how I will cope if he does pass In the next 2 weeks  It breaks my heart he may pass without his wife by his side.
