I'm smoking myself to death again. It's an addiction. Is it?

Life's an addiction, my narcissistic traits, am I a sociopath? I do have anger, despair. Bipolar and comorbidity. Especially alcoholism, Social Anxiety and some PTSD stuff. I'm no expert on any of those things, I just wanna figure stuff out for myself. Thinking like I'm a bit of everything put my mind at ease, I guess. Was a good experience, the first one after about a month of no cig was damaging to my lungs. I can see some good points in my smoking habit, may push myself even harder on other area of my life. This is just interesting to me.
