Is my orchid dying?

[Lisabeth_02]

We bought an orchid, I'm sorry I can't tell you what it is. Its beautiful, that's what it is. But it unfortunately wouldn't be the first orchid I have successfully killed. I water it with 3 ice cubes, or the same about of liquid water. But I do this randomly as I think of it, so it more than often goes without. The flowers on one of the stalks dried up and fell off, and then the stalk started turning brown. I figured this was normal and maybe I need to cut the dead stalk off? But then one of the leaves, the smallest, that was once a dark green leaf, was turning yellow from the bottom up and when I touched it to examine it, and it fell off. Now I am in a bit of a panic. I'm thinking it needs to be replanted, but I'm not sure. Maybe its starving and needs fertilized, I have no idea.
