Hi Stephen - if you really dont know which direction to go in, i think the first step should be some career guidance.. either with a trained professional.. or with books and online research (if you're able to be objective etc).. once you see what you're suited to, it should be easier to work out the steps to get you there
alternatively, try finding some volunteer work or new hobbies that might expand your outlook and give you some ideas (gardening? working with children? web design?) there really are so many options! good luck
