Just been told my boyfriend is dying

Hi all...I recently got back with my boyfriend after a break of a few months. We had been together for five years before that. We had not been spending enough time together because of outside influences, but realised after some time apart that there was something left to save and were taking things a day at a time.
He had major surgery to remove a tumour from his throat and had to learn to speak, eat and swallow again back in 2018.
Recently, he found a new lump at the back of his mouth, so got it checked out. The cancer has returned, but has spread to his lungs. Two days ago he was told that there is nothing they can do and he has around 9-12 months left. I'm obviously devastated, angry, scared and worried. 
I'm not really sure what im asking by posting on here, but I wanted to let it all out and be around people who understand. x
