Don't Blame the Sobriety for the Emptiness, Blame the Weed
Now that you've quit, you are likely dealing with an almost unbearable feeling of emptiness. Hang in there. It will go away eventually. And, as bad as you feel, it is well worth the wait. Your brain is busy rebuilding the emotional infrastructure weed obliterated. Blame the weed for how you are feeling not the sobriety.
Whatever weed gave you artificially it stole from you 10x over. Each puff digs a little pothole your brain must fill. After years of use, that pothole becomes a canyon that weed only temporarily fills up while simultaneously digging that canyon deeper. This is why many of us got to the point where we had to use more and more just to get back to feeling normal.
After a long period of sobriety, there is a tendency to associate the weed with the sheer pleasure it gave you. This tendency often leads to relapse, since it fails to account for the price this pleasure exacted from you. The price is the long-lasting symptoms of physical and psychological withdrawal - the sense of emptiness - you must endure before you can get a true sense of what sobriety truly feels like. Only once you've gotten past the withdrawal - once your brain finally repairs itself from the massive emotional deficit weed carved into you - can you truly experience what sobriety feels like. For someone like me who used 30 plus years (day 12), I fully expect the emptiness to linger for a year or more. And I've relapsed on many occasions in the past out of sheer impatience. I mistakenly blamed my sobriety for my feeling of emptiness. I now blame the weed.
