At what point are you going to leave your home country

I keep wondering at what point we need to pack up and make aliyah. It would be horribly difficult for us (autistic son, I'm homebound with Stiff Person’s Syndrome, multiple pets, etc) but I will wake up in the middle of the night and wonder when it is just safer to leave.

We have had dead rattle snakes left on our front step (we are in Texas) and I've had situations waiting for doctor procedures where people were going on group antisemitic rants while I was sitting there.

What will make you leave where you live and go back to Israel?
