so today my car started to loose power and only rev when in gears, now it doesnt go anywhere when its in gear it is like its in nutural, no gears work not even reverse, clutch cable is fine, any possibilities?

You need a new clutch.

Yep- what Reed says-

 

If it hasn't done 150,000km then its too many wheelies or driving with your left foot on the clutch pedal. Met a lady last week who's X-Trail clutch lasted 50K because she rests her foot on the pedal.

 

You might have ripped the centre out of the plate, that happens too.
