Who says you can't isolate? Sometimes it really helps me re-ground. My job is fast-paced, I'm introverted, and I'm going through quite a bit of shit. Not only do I not enjoy crowds of people or even chit chat with a few most of the time, I find I feel best if I hang out in the corner of the smallest room in my house. Once I'm more grounded and rested I get out into the world. I've picked a few choice things that I stick with, like a 12-step group (alcoholic), a meditation group, and usually saying yes to small birthday gatherings...lately mostly NO THANKS to big parties or gatherings in crowded bars. Part of it is just maintaining a low level of arousal that lets me rest through this stage as I need it. But I'm also learning about having some boundaries and not feeling guilty for it. If you can find one or two things you enjoy getting out and doing, or a couple people to stay in contact with, that's helpful. I don't want to be totally isolated for the longterm either, but I'm mostly over my never-always thinking. I'm pretty isolated now. It is a recurring pattern. But I'm safe and I don't actually miss human contact, at least not right now. I don't feel lonely.
