@justy I am so sorry to hear what happened but it was absolutely not a "complete fail" as you labeled it. It was an amazing attempt by an amazing person to do everything in your power to get better for you and your family. It sounded like a very strenuous trip involving many different parts and there is no way I could have done this either.
I have a few logistical questions-
First, what is Eurostar? Is this a train? Is there any way that you can do a direct flight from Wales to Belgium without all the different legs of the trip? If you had a wheelchair at both airports would flying be possible? I know it might be cost prohibitive but I was wondering if it was logistically possible from a health perspective?
Second, if flying is out, is there any way to stretch out the journey so it is not all in one day? Meaning can you plan to stay longer with your mom before embarking on the second part of the journey?
I don't think you have lost more ground and if you had forced yourself to push through, you may have gotten more ill than resting at your mom's and figuring out a new plan of attack.
But I totally understand the sadness and disappointment and would be feeling the exact same way if the situation were reversed. Is it possible to do what
@Daffodil recommended and get the IVIG to take home to administer or is it too dangerous to do outside of a doctor's supervision?
Sending you a big HUG
