The sterile white walls of her apartment seemed to close in on Clara. Sunlight streamed in, but did little to warm the cold, empty space. The apartment, once filled with laughter and bustling activity, now felt like a mausoleum. Her relationship was over, but she couldn't bring herself to go out and see her friends.

She sat on the edge of the sofa, staring at the television screen. The vibrant colors mocked her inner landscape. The constant, draining fatigue made every task feel monumental.

A notification popped up on her phone: a new message from a support group. She hesitated, then opened it. A woman named Evelyn had posted about a new doctor.
