Wow! Even a mother's unconditional love cannot cure a disturbed mind. Unfortunately if he thinks he doesn't have a problem "HE" doesn't. It will always be somebody elses problem. How ever when he has to start being accountable for himself by himself "without momma's or somebody elses help" it may become easier for him to admit he has problems. Don't "love your son to death" he needs real help tough love maybe the only option. If you enable you can kill.
