....making abrupt decisions with virtually involuntary forceful enthusiasm.
thats my definition of impulsiveness and I also call it the "crashlanding" feature of my life which is more just about me than any dis-order if I go by the diagnosis?....
The formal bpd criterea only gives a few examples...like spending, driving like a madman/woman, binge eating.
But what about where all that comes from?...it's impulsive thinking. Gotta do somethin' full on...and gotta do it now!....surely?
there has been nothing stable about my life because of it.

...crashing out of relationships and landing in another
...crashing out of friendships and landing without friends
...crashing out of one job and landing in another job
...crashing out of a place I live and landing in another place
...crashing out of an addiction and landing in another one
...crashing out of study and landing in aimlessness
...crashing out of money and landing with none
...crashing out of being a good citizen and landing in trouble
...crashing out of being well and landing really sick

sorry...another HUGE list...theres probly more?
