Questions about example sentences with, and the definition and usage of "Oooo"

A: OOOO(City name) is a pleasant city to live, yet I rotted away at home. I have become small and alienated. I only went to work and home. When I think about it now, I am sorry for myself that I could not enjoy *my time* Back then, I really could not think of anything. *even though the* sunshine, *the* wind, and *the* smell of leaves. All the ingredients for a beautiful day *(were there)*, yet I felt * hollow inside. I could think of nothing but the incident. When *these* kind of unfortunate situations kept *happening* my mind went blank. I was afraid of the sun coming *out* the next day when I *went to* sleep every night.

I added * at the places that I made changes, hope this helps
