Excepting for a minor correction and two deletions (highlighted in brackets)the paragraph is fine.
I had just come back from playing outside, that my mom told me we were going to a wedding ceremony. It was one of my cousin's wedding. I didn't at all feel like going anywhere. My whole body was a total wreck, and the hot temperature had really sapped my strength. Quiet honestly, I was too tired to do anything or go anywhere. I just wanted to knock myself to sleep, but my mom told she couldn't leave me home alone, because my granny was also going. So willy-nilly, I had to agree to go with. My mom pressed for me the clothes and told me to shower.
The wedding was at XYZ lawn. It was quite a prosperous marriage lawn and was very well-decorated. There were lots of popcorn sellers and balloon men standing outside the lawn. People seemed to have spent hours on gussying (up) and looking good. But nothing seemed to be captivating me. While I was rolling my eyes looking for someone or something interesting, I suddenly glanced at a familiar face among the crowd. Oh, it was my very best cousin plus friend, Spencer. I was very happy and (kind of) charged to see him.
I had a lot of fun with him. Then it was dinner time. The food was very good. A few minutes after the dinner, my dad told me we were going home. By the time we got back, it was 1 o'clock in the night. I instantly changed my clothes and rushed toward my dear bed.
