How do you write "empty inside" in Chinese?

Empty inside / 內心空虛(内心空虚 - Simplified)
I just input “empty inside”into the input box of my Google Translate, and the output is“內部空虛”. This is the best what Google Translate could do, because in a lot of situations, inside means“內部”.
If “empty inside” means someone just can’t stand life, is grief or anger, or nothings gone right for him or feels lonely. In Chinese, we would say “My heart feel empty” or just say “I feel empty”.
I’m not good at English, cos, I’m a English learner here in Taiwan.
If “empty inside” has a same meaning as “my heart feel empty”, then the correct translation of “empty inside” would be 內心空虛
Pinyin : nei　xin　kong　xu　

I just checked Google Translate. In this case, it's correct.
