When we say "somebody's heart sinks", it means that someone is feeling disappointed, upset or hopeless. It's like when you were expecting something good to happen, but then you find out it's not going to happen and you feel really down. For example, if you were waiting for a friend to show up and they call to say they can't come, your heart might sink. We often use this expression to describe a feeling of sadness or disappointment.
