When writing about what you feel it usually is a opinion essay or argumentative in which you are trying to convince them that your feeling towards a subject is right. Usually it depends on the subject.
And outline for your own feeling’s summary (1-2 paragraphs) you would include how you feel about that subject and any supporting details of why you think that. Usually in the summary you would use “I think, I assume, I believe, To my belief,” as transitions within the summary.
The summary should be a short description and should not go into deep detail but still should allow the reader a deep essence of what they are reading.
I hope this helps!
