Hi Eddy,
+1 for what Peter wrote.
I would suggest getting the 'Toolkit' publication by either ringing the number above, or going to 'Information' at the top, and scrolling down to 'Our Publications' and clicking on 'Toolkit'. I found getting information and understanding helps.
You can also download it online.
Lots of members here have had similar and much higher PSA levels than yours, so don't dispair.
Keep us posted and all the best.
