I disagree. The mental part of addiction, the drive to do more is the harshest part in my mind. Even with things like opiates and alcohol, which make you so physically ill, well normally a person wouldn't do something which makes them sick in the end right? Even with opiates I think the primary compulsion is just that, a compulsion. It's all in the mind. Otherwise, no one would decide to use or quit, yknow what I mean?
Crystal meth is the most mentally addictive drug there is, even more than crack. The relapse rate is 92%. No way are 92% of any demographic dealing the weakness of a feeble mind and absence of character. I know you're down on yourself, but try not to be so much. You can live with your decisions, good or bad, and move on to the next day without being in the same rut you are today.
Give yourself more credit. It's one of the hardest things in the world we're dealing with. The battle of our minds against hard chemical drugs, crystal meth in particular. We're not weak, we're not feeble, we're actually pretty fuckin tough to be living through this and all the negative consequences involved and still able to get up and deal with the day, at all.
Bad day? Okay. What can we do to make it better? Just enjoy the buzz while its on, do things we like to do, and pick up again when we're down. By picking up, I mean ourselves. Dust off and face the day. If we give in again at some point we're not failures, ok? You're not a failure. This is hard and takes many efforts for most to conquer. People do conquer, and so can you.
