He spent his days in a haze, the hours blurring together. He’d lost interest in his hobbies, the things that once brought him joy. The world felt grey, the future a blank canvas he couldn’t bear to look at.

He felt disconnected, adrift. His mother knocked on his door, her voice filled with worry. He didn't respond, the words lodging in his throat.
