Placement or Home Health

I’m at a crossroad.  My 75yr DH has landed himself in the Psych Unit.  He became very agitated.  His reasoning is broken and there is no real reason for his behavior accept his delusions about money and his disabled truck.  He also hallucinates and wanders.  He is no longer able to talk coherently, except for a couple stories he can tell but mixes them up a little.  While pacing,  ranting, rubbing his arms, and checking the garage every few minutes, I understood him say “it’s not IF but WHEN I commit suicide”.  Then I heard him open the garage door.  By the time I could put the dogs up, find my purse and keys, he had already walked to the highway.  I picked him up and brought him to the ER.  They are keeping him to observe and then prescribe different meds for his behavior.  They called and asked if he would be coming back home.  That’s a loaded question.  I visited him and he hates everything, they are all idiots and he says thanks for treating him like a turd.  That’s all I could understand after one hour visit.  Obviously not on the right meds.  Here’s my real thoughts.  Hurricane Francine will strike this afternoon.  I asked if he knows that and he mumbled it was on TV.   That’s it, no concern for me.  The staff says he is acting grandiose.  Our last outing he made two racist remarks and I scolded him.  The part of his personality that remains is horrible.  I’m thinking about placing him.  My mental and physical health is declining, I have an autoimmune disease and this isn’t helping me.  I loved who he was, but not what’s left.  He won’t see the actual doctor until Friday, two more nights.  The staff will have time to observe and take more notes for the doctor.  My SIL wants him placed.  Their family has this disease in their DNA and she has been a caregiver before.  She is 80 and has neurological issues.  The other sister now has Alzheimer’s and taking meds to slow progression.  His mother and her two sisters died from Alzheimer’s.  We all know where this leads.  I’m not handling this well.  Im 65 and have only one son to help with heavy things.  What are some pros and cons for him to remain at home under my sole care?  Is it time for professional home health or placement in the VA home?  We have a LTC policy that covers either.  You guys are amazing and I’m blessed to have found this group.  TIA
