Stage 4 lung cancer

Hello everyone, my partner was diagnosed with stage 4 lung cancer spread to the brain and liver. He now has 14 tumours on the brain and doesn't have treatment until another 2 weeks. Has anyone experienced this and got any advice on how I handle the fear I feel. My partner is 60 and we are very much in shock. Thank you. 

Me again, my partner has deterioted rapidly in the last 12 hours and I don't know if I should ring 111. I have no one to help me.
