You worry me slightly ..

If you did you Skills test in December, I would have thought you'd have been flying your socks off in the last 11 months to reach the min hours to start your CPL (its something like 150 hours).
To be worried that your PPL will lapse, sounds like you're not flying very much.
And you need to brush up on your research skills. You should know the "12 hours in 2 year" rule from your Air Law, but with a simple google search I found the answer in seconds.
