My experience with disconnection in a non-scn-related but very similar situation:
This is a very short version. I may post a longer one in it's own thread somewhere in the future.
My child was maybe 6 or 7, when one day s/he called me to let me know that I was a sh*t father and s/he wanted nothing to do with me anymore, never ever. Ouch! That hurt. There aren't many things in this world that can hurt me, but this was the most effective blow possible against me. It also was the only one that worked - all the previous blows had failed.
So what could I do? Well, I just let him/her know that I accept his/her decision, and will never bother him/her again, but I also assured him/her, that I will be there for him/her, whenever s/he wanted me to, and that I will never be more than a phone call away.
Long story short, it took 7 years and some "special circumstances", for him/her to call me, but s/he did, and we are in close contact ever since and spend many good hours together.
Why did I write all this? I wrote it to let you know that no decision is final, and that whenever your loved ones begin to think for themselves, they might change their mind, and they probably will.
If I were in your shoes, I doubt that I would do routing forms or any other of that stuff that only exists to f*ck you over again and again , until they've squeezed the last drop of blood out of you and finally let you go. I wouldn't keep up with that crap. I would just go. Your friends and family will be back in your life once they've begun to wake up, I'm quite sure about that.
Just don't let the false pictures of you, that scn gives them, affect you. Correct the misinformation if you have the opportunity to do so, but until then, just shrug it off. There is nothing else you could do anyway. You just follow your own way, which I hope is the shortest way OUT.
