One long attack? Or a series of attacks? At my worst, I had about 40, a day. My adrenals were a wreck. But, each one lasted probably 10 minutes. I'd find something to do - to occupy my mind. I'd watch tutorials on interesting projects. I'd work on my art.. And... my house was spotless.
I have adult sons who suffer anxiety, too. They have found some nighttime relief with weighted blankets. Perhaps that's a tool worth considering? Look up some testimonials. I also sometimes employ guided meditation. There are videos that you can listen to, and practice in your own home. Check out YouTube. And then there's music my son finds very calming. A channel called Lofi Girl, that is available on Rumble, and probably YouTube. He shared that with me, and I listen to that a lot now, too
I don't mean to minimize your feelings, Jared. Anxiety is no fun. I just mean to offer you hope - and sometimes it helps to know you're not alone.
