I don’t think there’s anything wrong with saying you are angry. I think I would be too. Angry I don’t know what’s happened, angry that although the most logical explanation is that she drowned in the river but there is no trace, angry that the police seem to accept this explanation and focus a lot of attention on body retrieval. Angry at her if she just left herself and has allowed this media storm to continue and not been in touch (because this would be what I would want to believe to be true- that she is perfectly fine and safe).
