For me, I find some background noise to help. Not like music or audiobooks, but simple sounds.
Sometimes I really just feel like there’s too many people and things going on around me, so I find a video on Youtube of forest noises with wind in trees, birds, etc.
I find rain really calming, so I’ll play thunderstorm sounds combined with a fireplace sound because I always found both of those calming as a child and it’s followed me into adulthood.
I used to try to pray during those times to get myself to calm down but my head just wasn’t having it. I felt terrible that everyone would tell me to pray but I couldn’t finish a decade of the rosary. I thought I wasn’t trusting God enough. I’d try to double down on what I was doing and feel even worse when I just could NOT concentrate and stop thinking about what was bothering me. I’d be tossing around in bed, doing up-downs in my chair at work, walking laps around my living room, etc. until I could get my head full enough with rain noises or birds chirping to settle down and do what I needed. Eventually I’m calm enough to write it down and then find it doesn’t bother me anymore.
Edited to add that I got the advice from a therapist when I couldn’t settle down that I should find ways to distract myself to give myself time to process what was bothering me in pieces. The sounds were helping (really figured that one out by walking, but where I live I can’t get quiet walks in now), but once I added writing I found my process. You might need to find your specific quirks to help you process your thoughts and fears without being overwhelmed. I definitely recommend talking to someone to get some advice. I only had to talk to someone once and was fine on my own afterward. I just needed an outsider to give some thoughts.
Apparently my unease and distress shows itself in making me want to move. Turns out I find contemplating God’s creation in rain, birds, reminders of people doing simple work such as sweeping and cooking, etc. is better for me. No specific prayers or goal, just listening to different aspects of creation and life. No talking though. If the recording has talking and whispers it undoes everything.
