I really feel for you - that's a tough situation to be in. You've done a great job in sticking by her and getting her the help she needs, even though it must be difficult to see her in that situation. I'm sure she will appreciate it once she's better. It's now up to the professionals to do their job.

In terms of the holiday, I'd start by checking how you paid - some credit cards and bank accounts give you insurance cover in the small print.

I'd then try emailing the companies and explaining the situation. Whereas officially it might not be changeable, if you provide evidence of your situation, and you're just asking to change the dates you might find that they make an exception. There might be an extra fee required, but this could resolve your issue if its not too much.

If it's not possible to change the dates, it should still be possible to at least amend the hotel booking, if there is someone else you can take - a family member or best friend perhaps who can look after you?

Ultimately, if there's nothing else you can do, I'd just go. Make sure that you've organised for her loved ones to check in on her and set up a video call every 3 days to hear how she's doing and put your mind at rest.

Also, I'd set yourself up with some telephone/video counselling, booking sessions for every other day that you're there. You're likely to feel a bit lonely at times and that can lead space for ruminating to creep in. Having a professional to talk through how you're feeling could release some of your worries and allow you to get the proper relaxation and recooperation you likely need. Some workplaces have counsellor phone lines as part of their benefits, or you could sign up to Pirkx, which includes professional counselling on the £6 per month package (cancel anytime). I don't work for them, just think they're a great company.
