I don't know that the "specifics" of your case will be a problem for you, its more that you were Baker Acted because you didn't/couldn't take care of yourself and that isn't really an issue? I think your housemate could say whatever she wanted to get the cops out there but then they'd see for themselves what was what and they decided you weren't "with it" on their own. I don't think it was her story that got you taken away but your behavior/how not together you were when they came to check it out.
