If this is the end

8:43pm, apartment, Chandler, Arizona, Friday night, March 18, 2022. My betta fish looks sick. I am not sure what is wrong but there seems to be an infection around her gills. I cleaned her tank earlier this evening, then went to the pet store and got a product purported to promote healing. Hopefully it works and she will be alright. I am emotionally attached to that fish. My daughter picked her out over Easter weekend last year. Since then, that fish has been my loyal housemate; eagerly greeting me when I get home from work, hoping for a couple of pinches of food before I settle in for dinner and swimming to the front of her tank every morning before I leave. She is such a part of my daily routine, I would be sad to lose her if this is the end.
