I've tried this "focus on the present" practice called meditation. It is easy to sit with an empty mind but it is not easy to allow myself to fully immerse in sensation because then pain that feels as if it is in the body comes. Recently it's been able to ease into just sadness but it can still be pain. When it's pain, I cannot stay immersed in the body. It is not tolerable like that. When I'm lucky and it's instead refined into sadness, it's manageable... Has anyone ever heard of this?
