New to this community, looking for support about how to cope

My father in law has terminal lung cancer. He is 91 and still lives at home, on his own. He is not having any surgery or receiving any treatment. He gets palliative care through local community nursing service.

I thought I was coping ok, but I’m not. Over the last few weeks, his health has deteriorated quite considerably, and the District Nurses are now telling us ‘it’s weeks now, not months’. It’s hard. Both my partner and I work, alongside caring for my father in law. Whatever we do, it never feels like it’s enough. We’re lucky I guess that we only live 30 minutes away from him, so can get there quickly if we need to. But it’s hard, and getting more so as time goes on.

I’m trying so hard to be strong for my partner and his Dad. But I do feel like I’m on the edge of being ok one minute, and not okay the next. I feel very fragile, and it’s affecting other parts of life - relationships and friendships, work, mental health and anxiety, sleep.

I’m interested to hear from anyone that can help me (and my partner, his son) to understand and process what’s happening. And how do ‘prepare yourself’?

Thank you in advance.
