Marijuana Addiction...help me?

i wanna just sum it up. I have no money, job, car, license, or insurance....i live at home with my parents. all my friends smoke. my parents smoke. I've sold my own possessions just to buy weed and beer. These are not "hardcore drugs" but i guess because i won't touch hardcore drugs...these are the 2 things that i'm addicted to the most and are harming me. Today i've been without pot for hours and i wanna hurt myself. I'm an ex cutter and for everytime i kick an addiction i harm myself. I was on medication until i failed classes in college and dropped out. I was also abusing the medication i was given as well. It seems as if every solution that's been givin to me, has only worked temporarily. Suggestions such as being more active and eating healthier does not work due to me being financially in bad shape. No money to buy the help...no money to do the drug...and i'm just stuck in the middle of this...in really really bad pain. Now what?
