Hello. You did not enter the text to which these questions refer, which makes it impossible for them to be answered. However, I will try to help you in the best possible way, explaining how to answer them.
In short, it is only possible to answer these questions by reading the text. After reading this, you will be able to identify whether the speaker has symptoms of nostalgia or trauma. This is because nostalgia is a feeling of lack, where the individual wishes to return to a place that he has lived in the past, or wishes to return to a time, or a situation that he has already lived in the past. The main characteristic of nostalgia is this desire to return and live an experience again. The trauma, in turn, also refers to a feeling of place or person that the individual knew in the past, however this sensation is bad and the individual does not want any of these elements to return to his life, that is, he does not want to live that experience again.
The pain presented by the speaker, whether caused by nostalgia or trauma, is directed to something from the past, which will be presented in the text, probably in an explicit way.
