You're definately NOT alone- I feel exactly the same way- worry is a constant with me, and from the posts I have read here on SC, it seems that a lot of cysters are also dealing with the same thing.
Pretty frustrating, eh? In my experience, meds did nothing to stop the worrying- it's just something we have to deal with one day at a time.
Hang in there- we're all in this damn PCOS thing together!
