The prison feeling will end once you're past teen years and live on your own. Whatever you do, unless you're a lucky sports player, it will still be there until you're out of those years.
Until then, you can use the time you have to educate yourself. You have internet, use it to perfect yourself at some areas, and gain a general knowledge for all kinds of things. It will be of use for later years, when you won't be able to read about random stuff for hours and you'll have to work for living.
Also, try hitting the gym if possible. It will make you feel good, look good, and stronger both physically and mentally.
Don't be sad about not having a 'transport'. It's too overrated thing, trust me.
