Addiction of Smoking. Kindly help me.

Hi Doctor, My name is Amit Jha. Currently I am under depression, stress or what ever I don't know but I have no passion or love for my life. I am alive but internally I m dead. There are so many reasons of or I had just made a reason to make myself chill, I don't know. I am person who is hunger of love and respect but unfortunately I didn't get these things. I am failed in my career, relationships and everywhere. Now I m a complete looser but I was not like this from early age. I was a achiever. Circumstances got changed and I became alcoholic, chain smoker. I started smoking weed, charas and brown sugar. I had left all other addiction but I m failed in leaving smoking. Smoking gives me a relax with tuberculosis. Now I m suffering from tuberculosis, stage 3 and still I m smoking. I feel sometime that this tuberculosis is a boon me. I will die in some months and get final relief. Kindly help me...
