My mom had relaxation tapes back in the day, they were cassette tapes with anti-anxiety narration and music, she listened to them while she slept. And her one coping mechanism that lasts til this day is she wears a rubber band on her wrist and snaps it when she starts feeling to inward. For her anxiety was due to inward-thinking, hyper focus on herself or things that could happen to herself, etc. The rubber band gets her immediately back to the now, like Gremlin's "this is what is really happening today" mantra.
