Personallly with a young son and wife with me, life is good in Qatar, our social life revolves around him anyway.
If you are a male and by yourself i would think it sucks, not much to do and not that many of the fairer skin (thats ladies if your'e not English).
Don't get me wrong there is probablly more world class events in Qatar than your normal UK home town, outside of London, but that is it. Brits will miss their local pub, I sure as hell do.
The golf club keeps me sane and having a host of sports channels does help.
I must admit I am the exception amongst my friends or workmates, most of them detest being here and they just live for their next R&R escape.

I would say just give it a chance, I have been on far worse assignments than Qatar, the locals don't bother you and also quite admire the Brits and have a real love for England (strange but true).

The weather is fantastic, the summer is not really a problem, sure it's hot and humid, but were mad dogs so it doesn't matter.

The traffic is shocking, compared to the North of England.

Take it as an experience of life, taste it and then move on.
