I have total empathy for your situation.
My 44-1/2-year-old son, who now is in the State Psychiatric Hospital
for the 3rd ?? time, has been in and out of my home numerous times.
I am so sorry to report that because of violent behavior
toward his family, friends and community members,
he is no longer allowed in my home. EVER.
Paranoid Schizophrenia is the most frustrating and horrible disease.
My prayers are with you.
Set firm boundaries and don't sacrifice your well-being out of guilt, fear, depression.
