It's a bit different with my sufferer, she's not actually the life of the party around others, but I definitely see that she puts on a mask around other people and tries to act as normal as possible no matter how much pain she has (emotional or physical).
It can be very tough sometimes to be the only one (besides her mother) to see how she's really feeling and therefore experience the bad moods and everything that comes with it. But to frame it different, it's also a great sign of trust, because she feels safe enough around me to show her real face and put that mask down. I appreciate that she is just herself around me, no matter how tough it may be sometimes to deal with the bad moods, irritability, emotional numbness and so on.
