I used to be like you Zina, terrified of not only snakes but spiders too. But I worked on my fears and educated myself on varies types of snakes and learned that they are not "scary" as you think. My colleagues at work say "I'm crazy" or "insane" but those are the kind of people that need the educating on these wonderful creatures. I find that having my collection of snakes helps me destress at the end of my day, as well as brings a smile to my face!
As for the spiders (Tarantula's in general), I over came my fears, but keeping them as pets was just boring to me. Guess I much more prefer the interaction, excitement and beauty of snakes.
