Dear Diary, Today my classmates and I went swimming at a beautiful resort to unwind with the girl I like, but I couldn't talk to her because I'm shy and have low self-confidence. So what happened is that even when we're together, we can't talk because of me. While we were on the trip, my friend made a joke while the girl I liked was next to him. Of course, the girl I liked laughed, and then the girl seemed clingy to my friend, so I was a little jealous after the almost two-hour trip. We arrive at the resort, and I'm even more jealous, because why is he talking to my friend even though he knows that I like him? I don't understand; it's like they're so sweet; they even slapped each other's shoulders while laughing, and while my friend and I were swimming, it was like they were showing off to her, so I became even smaller. I want to go home, I want to lie down, and I don't want my heart to be heavy instead of enjoying our trip. I'm disgusted with myself; why am I like this?
