I'm so sorry about your dad. I hope your mum begins to improve. I can't give you words to take away this pain - it must be awful for you and all you can do is be kind to yourself and do whatever you can for your mum.
It's very hard at the moment with regard to funerals. My mum died at the beginning of March - not from Covid 19 so we were incredibly lucky and were with her at time.
Her funeral is in late April, it's a very long process to get dates at the moment in some areas.
Mum's funeral won't be the one we had planned for her (we knew she was ill for a while and she'd told her wishes years ago). We can't have a wake - nowhere to hold it is open and, even if we could get somewhere, you can't have a gathering now. We already made the decision that it was immediate family only before the lockdown took hold as two of the family children have health issues so we can't take the chance.
The crematorium has asked that each individual family (i.e. me and my family, my sister and her family etc) sit 2 metres apart, spread around the chapel. So we've had to get a recorded choir piece for the hymn she requested as 12 of us just can't make the noise that a huge family could.
And, of course, we can't get flowers. Many florists have shut, some can't guarantee what they can get that far in advance. So we've tracked down a silk floral tribute and her coffin will have that and only that. It seems that, as you overcome one issue, another pops up. Like the flowers - we didn't even think about the fact that flowers aren't essentials! It's a funeral, you don't even think that flowers aren't 'essential'. I know many people will say 'you're being ridiculous' but the flowers became a huge thing for us - we were trying to fulfil her wishes even through we knew mum would tell us we were daft to even try. Someone's death is all consuming. You feel so lost that just being able to get the funeral 'right' feels like you have some sort of control. And now you can't even have that.
However, we've already spoken to our local minister about a memorial (or thanksgiving for the life of) service next year when, hopefully, all of this is over. We'll make that mum's proper service and it will be full of the people who meant so much to her, she'll have the flowers she requested and a huge wake to celebrate the time we had with her. It's something positive to plan, to work towards.
This is an awful time and my heart goes out to you. Once it settles down, try to go with the flow - it's the only way we've managed. You can't change this, you can't let it overwhelm you. We've just had to shrug at each stop in the road, take a breath and recite our mantra 'we'll give her that at the memorial' - which we will.
I do hope your mum gets better quickly. My thoughts are with you.
