Friend,

Doha is a very difficult place to survive, especially if you are here to enjoy your life. With the given salary, you could survive if you are bachelor. Take 3 K for housing (single bedroom,apartment sharing)and control your spending, then you can go on. If you are married and with family of two small children, you wallet requires at least 8K housing plus another 3-4K living expenses (take care of the saving). Say, your children goes to school, school costs itself may extend to 2K month.

Let us say, a family man without housing minimum 18-20K.

Bachelor without housing 10-12K.

Still, think again before coming! The other part may not be so green!
