Need your advice please?

Long story short I'am deeply mesmerized by the beauty of a young lady that I met at my university so I approached her and we began to talk and to slowly grew into a relationship. And June she found out that I've been depressed for the most part of my life and that I was smoking weed, and abusing painkillers to help with the pain in my life. She asked me to stop and for her sake thats exactly what I did because I did not want to loose her. But she received a teaching in Atlanta and I' am in california and the relationship is steadily starting to go downwards and I have been sober since May 1 not smoking a single joint or swallowing a single pill. And I' am starting to feel very weak and I' am getting these constant urges to smoke one joint and thats the last thing I want to do because I still have the hope she someday might call and dont want to lie to her and upset her. So do you guys have any suggestions to help me overcome my addictions I REALLY NEED HELP.
