you said take up martial arts with a friend and you said you know which one, were you referring to the friend or the type of martial arts? do you think martial arts is good for me by the way. also if the "you know which one", are you talking about a girl?

You are spinning your wheels and getting no where fast.  This is wasted energy.  Calm down and make some strong decisions for your own life...it will only come from you to be comfortable and do-able.

You will be moving to a larger centre (where there are more opportunities...even for entrepneurs) but not another country.  There is amateur theatre available...looks for of an interest than a career.  Time will avail itself to learning and growing there.  

There is education in your environment...a focus on what you want to do.  The computer field is a possibility following some training.  Restaurants open and close...unless there is a specialty, it may be a hard nut to crack.
