Dear Diary,
Today was tough. I had a heated argument with Alex over something that seems so trivial now. We were discussing our plans for the weekend, and I unintentionally dismissed his ideas. He got upset, and I didn’t handle it well. I feel awful for hurting his feelings. He means so much to me, and I hate that I let my frustration get the better of me. I hope we can talk it out soon. I miss our laughter and inside jokes already.
Signing off with a heavy heart,
[Your Name]
