I know you probably have heard this more times than you wanted to, but you need to figure out how to get out of that 'gang' environment, get a better education and a better life.. Or just waste the rest of your life continuing to wait for him or any other guy like him to get out of jails.... It's your choice, make it.
You might think it impossible to do, but where there is a will, there is a way - so do what you have to do to make something of your life.
Look around you, and see if there are any other choices you can make for your future.. If not - move away from there and try again.
You talked about 'friends' - How about your family? Even a youth center is better than the streets or being all alone.
If you were a mother with a daughter your age, what would you tell her?
