As Sqad says - one single total cholesterol reading does not mean you need statins.
The total cholesterol level which you have been given is not a particularly good guide to your risk - it's the ratio of total to good cholesterol which is important.
There are many other things to be taken into consideration - age weight, diabetes , family history, exercise taken, blood pressure etc. before even considering starting statins.
Some advice here about reducing cholesterol levels...
