Hi jules2004,
Welcome to Cancer Chat. I'm so sorry to read about everything you're going through at the moment. This sounds like an incredibly tough time, made more difficult by what's going on with coronavirus.
Firstly it sounds like you're doing a good job of supporting your dad. The only thing to do in this situation is to take things one step at a time - as cliched as it sounds - and to follow all the advice and guidance both from your dad's medical team and also the guidance surrounding coronavirus.
Make sure you look after yourself as well - I hope you have others to support you or to speak to, and we are always here on this forum too. So no need to apologise for rambling - it's what we're here for. Sometimes just writing things down, and knowing others understand, can help.
In terms of the funeral, really that's a decision for you based on what you think is both safe and also best for you, your cousin, and your dad. I know funerals have also become more difficult due to the social distancing and everything else. Perhaps you could speak to your cousin about this.
Do also ensure you're following government guidance on shielding people defined as vulnerable, if this is appropriate.
As I say, I hope you find this forum a support to you.
Wishing you all the best,
Ben
