The day I stopped viewing myself as an ideality rather than reality, the day I realized everything I thought, felt, believed, and did was me and absolutely none of it wasn't, was the day I found an ability to change instead of deny.
Also, I'd say it is very easy to approach this with a defeatist attitude (consciously or unconsciously) if you have a belief that you are sick. Only time can fix a broken bone, so if your mind is broken, can you really change it - is it a futile effort to try?
Don't listen to a nut on the internet, though.
