Need to Ramble and.. Sophomore Syndrome

I know that maintaining your rank is hard but why should my rank fall in the second semester! I've checked and compared my scores from the last semester with the current semester, I've got less than three subjects where my scores fall and in the rest of the subjects I maintain my scores or even better, I have better scores. My current average score is better than the previous one. Blame myself for not working hard T_T

I can only blame myself... I got 'sophomore syndrome' or at least that's what my mom called. I became too lazy to read learning books, too lazy to go to school, I only got four to three hours sleep since I couldn't even close my eyes, my overthinking got worse, in short, I was too lazy to do anything related to school. I got stressed easily when I'm reading math or science, I could barely hold on reading about language and Religion.

Now that I think of it again, my current rank isn't so bad. Or... I hope so.

Has any of you experienced the 'Sophomore Syndrome?' If it's okay, would you please share your story?
