Hi,
I totally understand your situation. My family also lives in Europe and my husband had to stay home with our two children. In fact, this situation was what prevented me from seeking surgery in the first place. I wondered for a long time if I could make the trip by myself. In the end though, when my mother retired from her work, she flew all the way from Europe to accompany me for my surgery (which was a 5 hour flight from where I live).
Frankly, I don't know what I would have done without her. I had what I would consider a very good recovery, I was able to walk around after I was discharged. But still, having someone around to help with meals and all other needs was necessary. It was also important during the first few days in the hospital, even though I received excellent care.
Even though eveyrone is different, brain surgery is not a C-section, and there is no way to tell in what shape you will be after the surgery. This is the one situation where asking for help is more than warranted and I am sure your family might be more than happy to help.
This is my personal experience. I am sure that others will chime in. I have also heard that sometimes there are agencies that have nurses, or other stuff available at some hospitals who can help out with patients who need help. Perhaps you could ask about it at the House?
Regarding San Diego, there are people who had a bit of a drive after being discharged from hospital, although usually a long drive is no fun. For sure I wouldn't drive by myself. Would your friends be able to come and pick you up and drive you there?
Good luck with everything
