Lee, I for one know that things have moved on a lot in almost 10 years. Try to go back to your gp. There are a lot of different treatments for depression now, talking therapies, behaviour therapies and of course lots of newer antidepressants. Your gp is your starting point for a lot of these therapies.
By the way, you will never ever be told to snap out of it here. We all wish it was as easy as that!
