Churchill, who famously suffered from depression, called depression a "black dog." "Black Dog" found me. At first, I felt terrible! Because only I can see this "black dog" that is pestering me, and no one around me is aware of its existence! They will only think that I have changed - I have become decadent, decadent, and no longer like to laugh... So the first few days were extremely difficult! The mood is like a roller coaster, sometimes floating into the clouds and sometimes falling to the bottom. The ups and downs from the clouds to the bottom may take a month, it may be a week, or it may even happen in just one day... In general, at the beginning, I was dragged hard by the "black dog", bumped around, and my head was bloody... But now, I've had enough! I am determined to fight to regain my life from depression - a wonderful life that should be filled with countless laughter and splendor! I want to desperately create joy to make the black dog tremble. This is not enough - I also want to control it, ride on it proudly, and run crazily towards the vivid future! Why not? I will live and so will you. We will all live - live happily. After all, those short but shining days once existed vividly, and no one can predict the future, telling you that those days that make you happy will never come again.
