If this is not the son you knew, perhaps drugs are altering his behavior. There are agencies all over the country that will provide you with in-home support and counseling. Just let us know what city and state you are in, and we can connect you with help for you and for your son.
You mentioned that your son is ungrateful for the many things you’ve given him. Those things are privileges that must be earned by demonstrating good behavior. He has them all even though he is treating you worse than anyone deserves to be treated. Don’t attempt to take them from him but do consider shutting off service to his phone and computer.
When he threatens to hurt you, himself, or others, call the police. That kind of behavior warrants a psychological evaluation and possible treatment. Do not allow that to continue. You do not have to live in fear.
