Having done this with one of my sons -----Our Bud needs a full endocrine work-up. We need to see what's up with everything from all testosterone levels to thyroid et cetera. He needs an MRI of the brain. A small stroke can cause this kind of change in behavior. And a good evaluation for depression et al.
And he needs some REAL CATHOLICS to step up to pray the ROSARY for him STAT every day.
