I'm sorry to hear you're having to wait on further results. No wonder you are having trouble dealing with it. At least the surgery is over.

I'm not sure how you'd tell your friends this, or if it's even what you'd want, but a good piece of advice I got years ago when a family member was in hospital for some time was that it's better to show up just for five minutes every day or so rather than hang around awkwardly for an hour once a week. There was only so much to say, and they liked having someone check on them regularly and see how they were feeling.

Hoping for the best, and please post here as often as you'd like.
