Yustitia: These have different meanings. "I am bored" means that nothing interesting is happening. "I am boring" means that other people will think you a very dull person because you have nothing exciting to talk about or think about when you are with others. (Hope that helps.)

It's fascinating how the meaning of the root word "bore" changes so dramatically when switching between past and present participles! I am trying to think of similar cases of verbs where the past participle is used so frequently in this construction.

Many English students mix these phrases up, but they have two different meanings. "I am bored" means you feel like you have nothing to do - when you're sitting at home alone, or reading a boring textbook, you might say this. "I am boring" means you, Yustitia, are a boring person! So be careful you don't mix these up! :)
