Assuming, that I recently received unexpected news that both, surprised me and hit me emotionally. I'm literally lost for words and don't know what to say. I am not voiceless in a medical sense, nor out of words to a lack of vocabulary-knowledge. I am just overly surprised.
How would I express that in Russian? I came up with a collection of possible alternatives, but I'm not sure whether they express surprise, a form of mutism or simply a lack of knowledge.
У меня нет слов.
Я потеря́л дар ре́чи.
Мне не хвата́ет слов.
In my opinion, the first phrase fits best in order to express surprise.
The second phrase sounds more like a physical inability to speak (mutism)?
The third phrase, I'm completely unsure about. Also mutism?
The fourth sounds like a lack of vocabulary to me. Can I also use this sentence to express surprise?
