Technically, by definition you're an atheist. Don't be afraid of the word. It simply means "absence of belief in a god or gods".
You're also technically correct in not referring to yourself as an agnostic, since agnosticism is a position regarding the possibility of knowledge: specifically that knowledge about a given topic is unattainable in principle. This, I assume, is not your opinion.
Yet common usage gives rather different - and confusing - meanings to both of these labels. Instead of fighting a semantic battle against popular usage, you might be better off avoiding both terms, perhaps calling yourself a "nonbeliever". Depends on your patience and that of your interlocutors.
