For me, they certainly have been. One, in particular, has been extremely helpful to me.
We don’t do that anymore
When I feel myself slipping into a bad habit or a bad way of thinking I simply say “We don’t do that anymore” and it breaks those thoughts. Self talk works and I’m not sure why it works as well as it does but I will absolutely take it. When you’ve taken medications, upped the dosage on those medications, taken other medications to amplify those medications, and then had to start the process all over with a new medication it gets old. I’m not anti-medication, but I don’t want to take them anymore unless I absolutely have to so I will use whatever tools I can find to keep those thoughts away.
