Positive and Good News Only Instance

Does anyone know of any instances on Lemmy or Mastadon that focus only on positive news?

I’m trying to reduce social media usage in general but when I do use it I would prefer to be able to explore uplifting things only.

I know I can block negative stuff but I also like going an exploring communities I’m not interested in subscribing. It would be great to have a local feed that’s better for mental health.
