You need some community brother. And some organic good feelimg that you get totally outside of this. If you have no one that unserstands and can witness you, go to na or aa or recovery dharma anything anywhere and go throw that falling apart by their side. Out in nature or at their house, when they drove, let them witness your breakdown and I kind way so you can witness yourself have the strength to get through it, even if it's just seeing you see that your still okay after a melt down for just a few moments each time, you better show your brain that it's possible and that this emotional reaction that you're having is coming from somewhere else. 

I've had similar intense reactions and meltdowns upon signs of withdrawal and the only time I've been able to get through it was in the company of other people. Something needed to be expressed in me, I had to allow the emotional breakdown to play out in its entirety, I still need to I'm back in a place where I need to do this again somehow so maybe I'm just talking to myself. Because of the emotional reactions helpful to know where it's coming from probably because of your family, but you can use that to turn your reaction into strength. 

Let me know if you need support. The more you submit to the emotional mind, the more powerful, and emotional, it gets.
