Call child services in your town or city.

I have been kicked out when I was 14 aswell and I tryed to tell to those child servises and all that shit, but they didn't help. all they did is tryed to get me into those child houses without parents and stuff. but I didnt want that so I basically carryed on and started to lived on the streets. When I was on the streets I was going down down and down but I have cleard my mind and set a target for myself. After some time I got a job, rented a room in a shared house with the money that I earned, started to get used to it. It was really hard on the start but after I got used to it. I have met a lot of good people throught the time, the people that helped me and also cared for me.... three years past, im 17 now got my place, my things, a job, and now studying course at college, wishing to get a nice career. I think that its up to you. What you will choose is going to get you somewhere in life, no matter what you choose. There is always bad in life. but there is also good that might or might not get to you, depends on how lucky you are and what decisions you'v made....
