In desperate condition, i will try my best to get loan from my friends. If it becomes impossible, then i would try to sell my bitcoins but with half heart.
I think before trying to borrow money would be better if you sell your valuables can you sell, to avoid losses because of high interest when you borrow money, but I do not think that your friend will give you the loan interest?
Yes, if you can approach your friends and explain the problem to them i think they will be glad to help you.
If really the friends are good ones, they will be happy to help you with interest free loans thereby helping you to make very good relationship to bind more stronger. This must one of the solution, simply having some bitcoin saving for emergency must be another safer way.
