Hi Blackdragon,
It is very common for any one to experience a range of moods from daily situations, with us bipolars (if you have been diagnosed) it can be more extreme. I think your cousin would have put anyone in a bad mood.
The cutting I personally do not know anything about. But you are not a bit** and just because someone labels you as one doesn't mean you need to label yourself as one and especially physically.

Hope you feel better.
