Disinfected....
If you want to get Scn out of your head, I'd say read threads here - Seeing things for what they are is a good way to get things "unstuck". On this board there is so much info and so many diverse points of view - it's all food for thought and if one uses it as such, then there is much to be gained.
Whatever your situation, an objective point of view is usually a good one. Looking at your scene and writing your thoughts on it can be therapeutic, then posting it and receiving 'feedback' or responses can help ya see things from a different perspective, and can really help things 'shift'.
Ya can post anything and everything here, and from my experience, when ya post things of a very personal nature, that ya might expect an adverse reaction to, ya don't get one.....all ya get is support, and sometimes very good advice that ya wouldn't otherwise think of or info that can and does certainly make a difference.
I wouldn't bury any of it, or wish it to go away, but I think you've also got to give yourself a break. Like, get out there in life and put your attention on other things and other people as well.
Take a win on everything and anything, and don't kid yourself that ya could or should be able to deal with anything in one foul swoop. It's little steps that become giant leaps over time, and even then, it's not like life is always roses for any of us even though some of us may make it seem like it is.
You're here now. The more you read and the more you post about this stuff, the better off you'll be. And, for "exes", this board opens up all sorts of doors that ya couldn't or wouldn't imagine.
All the best with it all.
