is this bad

I get married in a month and people ask like omg are you ready and i kind of start stuttering and not answer with a quickness nd they assume im unsure. Im positive I want to marry him but i cant help it plus I already have anxiety so such a big decision thats only a month away with no support from family because they dont agree with us being young 21 and 25 and eloping in Vegas of course makes me nervous! Is this normal prewedding behavior or do yall believe like everybody else I should be saying yes with a quickness amd a smile when they ask if im ready .
