Puff you need to find a way out if you can. I can tell from your posts that Dubai/EK has finally got to you. It's irreparable...
Seriously you've reached the tipping point and need to break free, be it for less money or whatever. Think about your health (mental and pysical) and do yourself and your family a favour and take the leap.
The jobs at home (albeit for less money) are finally becoming available again. You won't regret it. You'll feel human again.
Hope you manage to stop the rot any further, keep your chin up!
