It depends what you call functioning I guess. I have BPD and I did well in school, managed to get a university degree (though I struggled with alot of issues throughout), have a husband and children and have had had reasonable jobs using my degree. However I haven't worked full time in about 12 years due to not being able to cope with the stress and unpredictability of my symptoms. T says that I am a high functioning BPD. I don't think it makes the symptoms any less intense though, you're just better at masking it.
