My Own "Smoking" Bio

I had my first taste of a cigarette when I was about 8years old. I have three older sisters, all three had already started smoking by then. My grandmother had just passed away and the whole family was taking it really hard. She was what held us all together. My oldest sister is about ten years older than me and she was drunk that night. Her friend thought it would be funny to give me one. So I took the cigarette from her and smoked it on my own. They got a bit worried because I never once coughed or choked or seemed unhappy about it. After that I smoked a cigarette every once in a while. By the time I was 14 I had worked my way up to a pack a day. By then my mother was having alot of medical problems and her medication caused her to have depression. She smoked about two packs a day. She never really noticed that her cartons of cigarettes were going faster than normal. I finally told her when I was 16. She didn't get mad. She didn't lecture me. She just said I needed to get a job because she couldn't support both of our habits. Lol, great mom right? Anyways so that's how I started and how I outed myself. Now I keep to about a pack a day, sometimes more if I am feeling stressed out. I have tried quitting so many times through out the years that I have forgotten how many times I have "quit". I always start again. With out fail. I've had three kids and for each of them I quit for the entire time I was pregnant. The day I would give birth I would start smoking again. I really truely want to quit but it feels like I've tried everything and nothing has worked. I don't know what to do other then just keep smoking....
