Haha Wow u sound like me three years ago, i use to sit in my room and play playstation 2 all day. So i sold it and all the games with it and got like £97. Rip off considering i had to pay over a £1000 for all of it, but better than nothing. After that i took up many hobbies and started meeting loads of new people through the
DJ Bootcamp and my socialness increased rapidly and helped me land a bar job as well.
So i think you getting a job will help you out and help you meet new people. Jobs i recommend for your age would be:
Types of Jobs
Bar: It is very easy to pick up there and you will meet a lot of girls and make many kool friends.
Hotel or hostel: I wish i did this, but yeah you again get a respectful job and experience, get to meet loads of people from all around the world and most importantely Hotel discounts!!!!!!!woooo.
Bowling Alley: Very fun and relaxing job, usually fun colleagues, get to meet loads of people who are enjoying themselves and increase your social levels to max.
Arcade: This one is pretty good again, You will have a good time and can even play some of the games if u got a laid back manager and again you will meet a lot of people.
Theme Park: Don't know much about this one, but i am sure its GREAT!
Restaurant: This one can be a bit stressful at times, but it will rely a lot on customer service and it might operant condition you to be more social with positive reinforcement with tips haha. Other incentives will be, FREE food well if you are good with the chefs lol. however cleaning can make the hours a bit longer.
Clothes shops: Nice if you have unisex store, my friend worked in one of these and said its a very interesting job and if you are just a bit friendly you will get quite a bit of interest from the girls, hell they might even ask your advice which thong looks better....(eye brow raise). Also will build up your own fashion sense so you will look good when you go out and you will get nice discounts again.
Cinema: These jobs can be quite easy money, but you can end up doing long hours for cleaning even after its closed. On the bright side the people who work there are usually your age and quite kool and down to earth, it is quite a fun job at times and you get to meet lot of people, however quite a lot of the girls will be on dates lol. Again DISCOUNTS, UNLIMITED cinema dates haha.
Supermarket: Hmmm these ones can not be very great if you are on a busy till, but it can be easy money if you don't mind doing repetitive tasks. You will gain customer service skills, but i don't think it will be the same fun/relaxed ones as above. Some stores i know do 15% Discounts on shopping, which can save quite a lot of money in long run.
Well those are all the nice jobs for your age i can think of that don't really need any specific skills and this will put money in your pocket and help you come out of your shell and meet people. You can also try some volunteering.
Also if you have a lot of free time and want to meet people you can do some of the hobbies i listed below, which would proably be quite easy to find in your area.
Hobbies

Tango
Samba

That is funny enough just some of the few, but i am sure you will be able to find something there. We are very lucky to live in age where we can learn pretty much anything and also at your age you will probablly find places and clubs that will do most of these things for free for you or very cheap. Take advantage of that now or you will regret it later if you don't. If someone in your college offers you a opportunity take it (not drugs...), like a party or if they are setting a school holiday or even just the chance to join a college club. You have to be a opportunist in life to experience new things and meet new people and you will be suprised you get a lot of FREE stuff.
Haha i was going to write a small reply, but ah well i think that should be enough. Let us know how you get on, i hope the best for you.
