From the moment he woke, David felt a dull ache behind his eyes. He’d barely managed a piece of toast before heading to his lecture. As he sat, barely paying attention to the lecturer, his phone buzzed. A link from his mum. "Thought you might find this interesting, honey!"

David clicked it. The familiar cadence of his writing jumped out at him, a stark reminder of his past self. He wanted to sink into the floor.

He shifted in his seat, his leg bouncing up and down. He felt a sharp pang of annoyance that he couldn’t seem to shake.
