I was about to say no... but thinking about it, that's just because I've used a different vocabulary. I don't think about running so much as about reinventing myself. This is how I see it. I don't have DID; enough people have described to me what that feels like that I'm confident in that. But I lack a core identity. It's like being one of those disco balls with hundreds of little mirrors on the surface that will reflect whatever is in front of them, sometimes a bunch of things simultaneously, but on the inside it's empty. Another way of putting it is being like a leaf in the wind, blown this way and that, with little will of its own. So if an attractive idea comes along, or a person with a stronger personality crosses my path, I'll be pulled in that direction and so absorbed that for a while I can fool myself into thinking that's who I really am. Like seeing the world through someone else's eyes almost. This makes me way too easy to abuse or take advantage of. It's gotten better over time; at least now I know when I'm doing it and that it isn't real, and my sense of places I won't go has gotten stronger.
Physically I've run away, or escaped, repeatedly. As a teenager I tried hard to find a family that would take me in to get away from my family, but everyone turned me down. I spent as much time away from home as possible. When my parents fought I'd run. Walking, riding my bike, hiding. At 17 I left home for good, moved in with a friend's family, which lasted until the friend's father beat her and I threatened to call the police and they said they didn't trust me anymore and asked me to leave. They would have given me time to find a place to go but I felt I had to run, and I left late at night and went over to another friend's house and sat in their garage until they got home and let me in. Stayed there for several months until that family had people staying that drank so much I wasn't getting any sleep, so again I left. Finished school and had no plans, so accepted an invitation to another country, a very unstable situation. Got into a bad relationship there and gave up my plans for university for this relationship. And so on, and so forth for many years. I've complained before about how I don't know how to decide what kind of work I want to do because I don't know who I am. This is the same thing.
I see what
@scout86 is saying, that it's all right to change your mind about what you want as you go along. I think there is a balance though. Having a clear enough idea of what you want and where you are going that you can hold onto that and solve the problems that arise on the way, while being flexible enough to tell when it is time to change direction. Being able to tell the difference between a reasoned decision to change your mind, and a flight reaction because you don't know how to solve a problem.
I'm becoming aware of black and white thinking in a lot of areas of life (and noticing myself using that term in a lot of my posts!). It comes up in any situation where I feel threatened. Unfortunately that's an awful lot of situations. Often I make the most obvious choice presented because making any choice at all feels better than continuing in that nebulous, uncertain area of trying to figure out what I really want. Like a deer in the headlights, frozen until it suddenly chooses a direction and bolts, even if the direction makes no sense. Making poor decisions just to make some decision, then getting there and realizing that doesn't work either. If I can manage to feel safer, or even to give myself some breathing room, hopefully I can make decisions I don't have to run from. And then there's the issue of distress tolerance. Staying with an uncomfortable situation because you know you can get through it and will be better for it rather than fleeing as soon as it gets uncomfortable. Being comfortable with small steps. Knowing how to work through conflict. And trusting your judgement enough to know when it really is time to leave. A whole lot of things are involved here.
Hopefully that made any sense at all! I'm not in a great space today.
