The above Acrosstic I wrote quite a while back, and still it seems a ground truth to me: most people who are doing drugs, even prescription ones, are essentially just lacking connection to the whole, and even to their own body. Instead of examining the negative feelings they have, they take substances that make them temporarily feel better.
Even me, devoid of smoking and drinking, still take prescription drugs, because without it I would become ungrounded, and start seeing the world as way better than it is. I know that eventually there will be a solution where I can ditch the meds altogether, but for now, I'll just practice gratitude until I get it right...
