sry to hear that dawn. your mum never have any therapy for her BPD?
i will say again medication does help people with BPD and the older we are actually less bpd traits we have..
here is a quote from a consultant on medication.
How useful would you say medication was in treating bpd?
Medication is of help in acute presentation of this condition, predominantly when there is lowering of mood or symptoms suggestive of abnormal experiences, including at times hearing voices. In the long-term some individuals benefit by the use of mood stabilising drugs, such as Lithium. However it is difficult to provide a definitive answer to the role of medication, as the predominant intervention is psychological therapy (talking treatments).
