I feel Facebook's taking over my life, I need a hobby?

Spend time on yahoo! instead of asking questions (unless you need to) you can become proficient in a field and answer questions yourself. You can also learn alot of stuff by watching youtube videos etc.
I can see that you want a hobby that does not involve a computer, so i would recommend training playing football, volleyball any sport that you enjoy really. If you are in school , try revising with your friends rather than on your own at your laptop if you dont already. You can also go out regularly maybe go to the cinemas, town and other social activities you might wish to participate in such as youth clubs at leisure centres.
