Old post I know, and OP is long gone, but I know we ain't the only ones out there. There's more people with DiD than most realize and there's no point in starting a new thread when all the information can be found in one place.
But yeah, I've got it, used to be much more unstable and I def wouldn't have been able to be on the road without a buddy. Being a homebum was tough enough. But now I trust myself to be alright(and a big reason why now I'm finally gearing up to go). I think it's real important to have a good set of gear and some reliable way of getting income(busking skills, government assistance, etc), plus trying to keep to bigger cities that are sure to have better resources.
Reason is, a big thing that triggers a switch to an unstable personality is feeling out of control and like I can't handle it, so that means I've gotta make sure not to take any big risks and to not push myself beyond my limits. Only you know your limits and your levels of stability, if you're already feeling unstable, best to sit where you're at now and try and wait to move until you're a bit more in control.
Orlando has a surprising amount of DiD folk thanks to the annual conference and local organization that has regular services geared towards the community(and other trauma survivors), if anyone is looking for a destination.
