Yes. If one of your friends called you up tomorrow and said they never want to see you again, you would go through withdrawls. You would go through pain and hurt and your life would have to adjust to it just like quitting drugs.
Right. Which means according to the "food addict" people I should stay away from all friends, get away from any modern conveniences (because I'm used to them making life easier), go into a cold, dark cave (because addiction to the sunshine might cause cancer) and just cure myself of that addiction to food and water. After all, it's for my own good. ;-)
