I found an interesting article that claims knitting can help with these disorders.

Here is an interesting portion:

Betsan Corkhill is a licensed physiotherapist in Bath, England, and a wellbeing coach. She created the Website Stitchlinks.com in 2005, dedicated to researching knitting as therapy, and has published a journal article on her research of the mind-knitting connection.

Knitting in particular works, she says, because it uses two-handed, bilateral, cross-body hand motions.

You are using up an awful lot of brain capacity to perform a coordinated series of movements," she says. "The more capacity you take up by being involved in a complex task, the less capacity you have for bad thoughts."

Corkhill created a knitting therapy program at the pain clinic in a local hospital. She describes success with using knitting to curb anxiety attacks. If patients can learn to understand their triggers and the first sign of an attack, they can whip out their knitting to distract the anxious feelings and calm themselves.

I don't know anything about knitting, but now I want to try.
