How far would you go do help your friend recover?

Let's say your friend, a very important person to you, is sick. They have insurance, and everything is covered, but for full recovery, special treatment is needed. And the hospital says, "we don't do it".

So you look in other hospitals, states/Lands, and countries. Oh... it's available as a private treatment, but the price is cosmic... $3 000 000.

so now... the question... how far would you go to help your friend? Would you take the highest possible loan? Would you sell your house? Would you beg strangers to donate to your friend's case? Would you ask for help from old power "friends" not knowing their price?

The whole thing is about daughters of my best friend, the twins prematurely born in February. After doing all needed to save their lives parents struggle with saving their health. Their sight is poor because required medical treatment damaged eyes. Two clinics offer experimental treatment and chances are 80% that girls will see without problems. The treatment is split for two stages and the whole cost is 1.5 million USD. Doubled, because there are two girls.
