Where can I get help writing sad stories?

Hi all, I really love reading stories that make me feel something deep—especially the sad ones that stick with you long after you finish reading. I’ve been wanting to write my own sad stories for a while, but I always get stuck trying to come up with the right tone and tragic twists. Does anyone know of any tools or websites that could help me write these kinds of stories? Something that can help me build strong emotional characters, heartbreaking plots, and endings that really hit hard? I’d appreciate any tips!
