Stand your ground Mouseyone, have him go back to the shelter. He will get better care at a facility that deals with Mentally Ill individuals.
Nothing changes if nothing changes. Remember, he won't make the changes, you will have to do that and then perhaps he will or perhaps he won't...but all YOU can do is change yourself, his changes are up to him.......you don't need to go down the rabbit hole with him.
Instead of putting all your energy into your son, take a break for a little while today and do something nourishing for yourself.
