do bpd's have ups too?

Wow, that is a mess of Dx's...you can have Axis I Bipolar II and Axis II BPD, it happens. Having ONE (ONE!!!) hypomanic episode really technically puts you into Bipolar II (means NOOOOO MANIC episodes EVER). That's what happened to me. You are a cocktail mess like most people with messes. This is why you add all those numbers and words onto the end of the Dx - Bipolar II Depressed, without psychotic features, chronic, bla bla. Ya, BPDs don't usually have happy highs....mostly. They do stuff to get high - steal, sex, cut - but it doesn't work so well on the 'Yay I'm doing so well in life' aspect. But having a high doesn't EXCLUDE you from having BPD - check the DSM!! - it just means there are more labels added to your chart (for you to love ).

Been thinking about this one for a while. I don't think I get 'high' very often. When it does happen it is usually for a really good reason and anybody would. Most of the time though I go between a middle ground and down. I feel ok or I feel intense hurt and pain. I have chased the high with alcohol, with sex, with drugs. I don't anymore. If I achieve something around work though I can become quite elated.. although it never last long. I seem to be a package of opposites. I can be quite narcissistic at times, but have a simultaneous low self esteem (which I know is impossible - but that doesn't mean it doesn't happen). It feels like two separate personalities in one body sometimes. But it's just badly regulated emotions.

That reactivity to positive events is called Mood Reactivity and is part of Atypical Features of Depression (or Bipolar etc).
