You are being hormonal and dramatic! LOL!
Seriously, I wouldn't tell you your numbers were good if I was concerned. Think about it logically. I can't remember your exact numbers but if you have a 1.2 measurement and a 1/4000 chance of Down's, you aren't going to have a baby with Down's. If you had a 2.7 measurement and a 1/4000 chance, I'd be more concerned. Or, if you had a 1.2 measurement and a 1/4 chance of Down's I'd be concerned. But the two combined is a very good thing. Your baby is PERFECT!!!
