I need help with addiction. I also have a persistent stalker.

I smoke cigarettes and I have tried to quit. I keep messing up. I want to quit smoking. Also I am stressed out by my stalker who is constantly stalking me. I have tried contacting police but they don’t listen. My Stalker does not listen to restraining orders. He is angry I had one before. I need help to make this guy stop hacking my phone,which gives away my GPS location. Now I don’t know what to do. I can’t do this anymore. And I need to quit smoking cigarettes. Help
