Yes. Because I have no belief in anything so death to me seems like an impending unavoidable black void of nothing-ness for eternity. I used to have bad panic attacks about it. I'm on meds so I don't fret about it. Not on meds because of that but they help. In a way I'm slightly envious of people who are religious because they don't seem to fear death because they have belief that there is something after. When you don't have that belief, you've got nothing. Its scary but you can't make yourself a believer.
