Sometimes I feel like a sociopath...?

I really am a nice caring person but over the past few months I've become more and more detached emotionally. Nothing really effects me and even when it does I refuse to show it.

I'm current have a drug addiction problem and have had a lot of consequences because of it including arrests, jail, homelessness, etc. Trouble it, I really don't understand them. They don't effect me. I see them as no big deal even though logically i know they are.

on top of this, i am also crazy impulsive. i do not think before i act in any circumstance. my psychiatrist told me he is ready to get rid of me as a patient because he doesn't want to be worried about what crazy impulsive thing I do next.

I think there may be something wrong with my frontal lobe...a former psychiatrist of mine said it might be under developed because of past trauma. i have no proof though and my current dr says thats bs.

ideas?
