Ok. Good plan.
Maybe find a short term rental in that state that's furnished.

Then you can have a place while you're in escrow on the house.

Take decision making slow- think twice, because of the mania.
Are you still taking your Meds? Get Pdoc to write a 90 day script so you'll have enough Meds for the move.

God Bless. I know you're thinking a lot about your children. Love you!
