Ah, the Glow. Enjoy your stay... yeah, I wouldn't know for sure but if you don't have any meds, it's highly probable that you played yourself into a highly radiated corner.
Most important tip for Fallout (and other - old - games): If you're heading somewhere you don't know what's coming, always keep a savegame from before you started your journey to certain doom. It's really the best smart thing to do.
There's always the possibility of your AI-equipped NPCs to blow each other to bits or you losing everyone and everything in, say, the Deathclaw basement of doom. Save often, as you would in any proper adventure game, AI-challenged or not.
I heard people (well, males) messed up their X-COM experience by going straight for Iron Man mode, and since a rough 95% of them have never played anything like X-COM before, they're either growing tired or getting a serving of castrating, debilitating depressions. Best fun since the invention of bigger dick competitions.
