I used to have this problem, and it can definitely become a big problem. You need your down time, and for me the evening is the only time I get it, if you aren't getting any other time, you'll probably go crazy.
I would try to push the crib. I used to nurse my son to sleep in my bed and leave him, and he would always wake up an hour or so later (which he wouldn't do with me). I don't like CIO, but I did do it when he was about 14 months old (not the scared or frantic cries), I had to for my own sanity. He now sleeps in his crib at night, but won't sleep in it during the day. He has changed maybe every month or so with his sleeping patterns for the last year (he is now 17 months old), normally because of teething or sickness, I just look at it each time as a phase, and work on it when I can.
One more thing, my son recently went through a week or two where he would not go to sleep in his crib, he would just scream like he was being tortured, so I would get him out. Turns out, we had put in a nightlight in there, and it was really scaring him, enough so that he wouldn't sleep. I also left his door open one night (I always close it), and he woke up in the middle of the night frantic, and that was the reason. Any weird shadows can be scary, try a nightlight (since she is used to sleeping in it during the day), different nightlight locations, no nightlight, just look around for weird lights and shadows and try to get her comfortable in the room with the lights off, not in the crib, but just with you, maybe playing.
