These past days I noticed that my attitude is getting worse. For example, I was at my cousins birthday and I didn't have the confidence to mingle with my friends. So I sat in the corner alone when suddenly one of my friends came and played a joke on me. I was not really in the mood for her jokes so I shouted her. My cousin and my friends looked at me and I felt like I was such a bad person but that wasn't really my intention. How can I overcome this attitude? I feel so different now, this is not me.

suggestion: consider the tense in which you are writing. Since you are telling a story you should be focusing on the 'past tense'. Also look to shorten your sentences rather than relying on commas.
