Coping Skills? Feeling Overwhelmed

What are some coping mechanisms you guys have/use for when you're feeling very overwhelmed?

I have ADHD and anxiety, and on a normal day I feel as though I have them pretty manageable. But in these last few weeks, life has chucked some mean curve balls at me and several new and unexpected things have come up. Since a lot has happened in a short period of time, I feel completely overwhelmed and I don't know where or how to start processing my emotions. Also, I feel as though it's making my ADHD and anxiety harder to manage.

How do you guys cope? I've spoken to my therapist and she taught me some grounding techniques to slow my heart rate down in the moment, but I'm looking for any and all suggestions!
