As an OCD haver of over 20 years, I find these suggestions to be pretty wonderful. In some of cases, these conditions can't be fixed by therapy, and/or the drugs don't work. Therapy is fantastic, but sometimes these things can be the difference between getting out of bed in the morning & not.
Finding these solutions can be absolute bliss - technology for 'hands-off' switching off things is one for me.
As with everything it's a balance, but if something small helps in a big way, that's a win for me!
