I had an ex girlfriend with bipolar disorder once who didn't really like to take her medication because she didn't like how it changed her from who she really was.... But then complained about how she was upset all the time (at 2 or 3 am after waking me up with random crying) about how she wanted to change.
Being all bleary eye'd and half asleep I'd go "uh... could go back to the psychologist, councilor, therapist, or back on the pills to see if they can help?" at which point she'd whine and yell saying "Stop trying to change me! This is who I am!!" after a brief pause of just looking at her to see if she had realized what she just said, I'd go "okay... uh... don't do any of that then?" To which she would reply with more wailing to the tune of "But I want to change! Why wont you support me???"
At this point I'd be imagining taking a pillow and smothering her face with it. It was a very nice thought.
Sleeping on the couch isn't so bad really, it's like camping!
