I completely understand
I really struggled with my late father's demise, in fact it was one of the most stressful periods of my life. I coped better after he was gone.
I don't want to compare a husband and a father, though. Funnily enough, I would not have commented, but just today, I was talking to one of Mum's friends who is in a similar position to you. With her husband, it's not clear at all how long he has and he's had to go into a home because one carer at home would not be enough. It's been going on for about 18 months.
She is actually going on holiday now and she agonised over it. She's much younger than my mum and she is going on holiday with her parents. They persuaded her that she really needed a break. She has also stopped visiting every day now. She goes every other day. It's just too much otherwise. She's retired so not having to juggle work.
If you are already talking with the hospice, then I think your situation is different.
I do understand how you're feeling and what you don't want to say out loud, probably. Neither does she. When there is no end date, it's really hard.
The first person I saw outside the family on the day of his death, I couldn't stop crying. And I had to explain, or I felt like I had to explain, I suppose there was no need really - I actually wasn't crying because I was upset. I was crying because I was absolutely exhausted!
Anyway, if venting on here helps you - vent away, you will not be judged 💐
