Here are some other ways to express embarrassment depending on the context:
* Nahihiya ako: I am embarrassed.
* Nahihiya ako sa kanya: I am embarrassed by him/her.
* Nahiya ako sa ginawa ko: I am embarrassed about what I did.
* Napahiya ako: I was embarrassed.
It's important to note that "nahihiya" can also mean "shy." The context will usually make it clear whether you're talking about embarrassment or shyness.
