Thanks for your prayers.
I'm so sorry to hear about your grandson. By being in the psych ward, have they been able to diagnose him? Sounds similar to what my older brother was like when he was younger and still is but in different ways now that he's 54 and he's been diagnosed with schizoprenia and schizoteple.
Growing up in that enviroment has been hell on everyone in the family, including my brother who probably suffered the most out of it all.
