Over the years my traits have changed. At 20 i was majorly needy and clingy. Not so much anymore (40) in fact i like to be alone. I feel like I fake empathy with many, yet I saw a tree get cut down and couldnt stop crying. My heart broke. I rage easily, but only with those I am vulnerable to - the ones closest to me.
doctor says bpd - but I was also told that 20 years ago, by a diff doctor also, before it became so popular. This Doctor i see now (psych) also says he sees cyclothymia in me which many doctors think is on the bipolar spectrum - https://en.wikipedia.org/wiki/Cyclothymia -- it seems to fit well.

If moods occur with no seeming trigger, they are often seen as bipolar - Mood Disorder
If these mood changes occur rapidly with a trigger, they are often seen as bpd. - Personality Disorder

K well, at least this is what I was told and I am sure everyone else was told something different, haha. I also have General Anxiety , which leads to constant worry and depression. Probably due to being over sensitive - another bpd trait. Dealing with oversensitivity causes lots of bpd'ers to shut right off.. as protection.. so yeah... uh... as you see, we all have so many different things going on and still get these similar classifications.
