How do you decipher if it's Anxiety or Direction when making a tough decision?

I have an extremely tough decision to make that I've been dragging out for months. Both options are incredible opportunities.
When I ask people for advice I know what I want them to say, which is not to do the thing. Does that mean that's what I actually want? Or is it just my anxiety holding me back from doing the thing? How do I decipher this?
