Many sociopaths and bi-polar patients experimented with illegal drugs before being diagnosed. Usually because they felt disassociated from their peers and had difficulty keeping relationships. The bi-polars felt powerless over their mood swings, and the sociopaths wondered why they didn’t really care about anyone. They lived a life of mimicking normal behavior. Of the two, bi-polars are more inclined to seek medical help.
