I've known for years that my 41-year-old son has had a problem, and only recently did I come to realize what it is. He is very paranoid. He distrusts people and has difficulty working with people. Presently, he has a night time job as a watchman where he has very little, if any, contact with other people. My son is highly intelligent and a very kind and caring person. He is also obsessive compulsive and hyperactive. He is wired differently than most people in that he drinks coke to excess (several liters a day) and prescribed drugs that seem to affect and/or help other people seem to have very little effect on him, such as Prozac and Xanax. I might add that he doesn't smoke and he doesn't drink but this is because he cannot handle alcohol and he knows this so he avoids it. Although he has a masters degree he will not pursue higher level jobs. However, he needs a higher paying job to pay bills and have a decent living standard. Although he is married, his wife seems to accept his eccentricities; however, I worry about what will happen to him when his father and I are gone and if he is alone in later life. How do you tell a paranoid person that he is paranoid so that he can get the appropriate treatment, and where would he find a psychiatrist who specializes in this disorder??
