healing techniques for friends

one of my friends is going through alot at the moment, he owns a film production company, he is producing a film which is suppose to be released in the cinema. but recently he's been really quite upset. On Saturday evening I started talking to him, to cheer him up I started to tell him Jokes on film making to making him laugh, which actually made him feel a whole lot better, this proves to me, that no matter how you feel in life, and I can tell you now, there are about 1 billion different emotions that you can be feeling, A joke and a good old natter like old times is the best medicine normally. don't block your friends out, they can help alot, I learned that with this friend and I made myself feel better as well.
