Before we can answer the question, is anxiety a sin, we must first look at how we determine if anything is a sin. But many people actually are looking at this backwards and are hoping that their struggle is somehow not a sin. But as we see as we look closer at this issue, there is great comfort for the Christian when we categorize something as a sin. Because as a Christian, we have something to do with our sin--leave it at the foot of the cross. Which is very helpful when we understand that we actually sin far more ways than we realize.
