Ghosting or dead

So me and my boyfriend we are both teens and we are basically young not even 16 yet so yea. He told me one day when I was at a therapy session that he had 2 months left to live. I was heartbroken. After that he told me his faith could change and I was a bit hopeful about it. But there is one thing that comes in our way, he lives in Ireland I live in Austria so we can’t see each other. And on 14/6/2024 he stopped talking to me I’m scared that he might be dead or he might just ghosting me. Normally this would not be a huge problem but he was my 1 love and I was bullied my whole life about my looks, my voice, I was abused and more and now that he is gone I can’t stop crying every single night. I am going to therapy but it didn’t help so I need some advice
