Ive been trying to quit.

Im an angry peraon i started smoking when i was 15 because i was pissed off at my dad and i never stopped. im almost 35 now smoking on average 2 packs a day for the past decade., ive been trying to quit for the past two months on tuesday night i smoke my "last" cig . My current work schedule has me off every wed&thrus. I havent been able to make it to thrusday yet. I just get so angry and i want to snap everyones head off, cigarettes have been my coping mechanism for my anger for so long, i dont know how to handle it. I dont want to snap on my friends or family. They dont deserve that which is the arguement i tell myself on the way to the store to pick up a pack. Im smoking a cigarette again but im not angry. I dont think i can break the cycle i want too. im a big guy im afraid of what ill do if i lose control of my anger. Ive tried nicotine gum in the past and it didnt work. I dont know what im expecting posting this here but maybe someone will know something i dont.
