This all started after the Stealing Independence quest with whatsherface (I'm blanking her name right now).
And before you ask, I checked up and down the Bug Tracker and found several VERY similar things wrong, but none of the fixes provided worked. I tried killing her via console, via normal ingame means. I tried disabling/enabling her. I even downloaded a fix from one thread that cuts off her "follower" status. None of it worked. I even tried the companion dismissal terminal in New Vegas at Gun Runner's.
The problem: I can't take on any companions (Except robots like ED-E and Rex). They all say something along the lines of "Well I don't think your current companion will like it very much" etc, etc.
Any help is appreciated.

Another thing, I tried messing wtih the Sydney fix load order but to no avail.
Edit: Also, she is currently at Underworld and DOES NOT follow me. She did for a bit until I downloaded the fix. But I still can't take on companions.
