Am I ruining my life?😪

My boyfriend and I broke up a few days ago. Sice the day we broke up, I've been drinking a lot. I didn't smoke but now I've the urge to do it too. I am not one of those girls that you see drinking and smoking and partying but now that's all I want to do. Please help! How can I stop doing this. What are other ways to get my mind of off things without hurting myself.
