Hello not sure how to start this off and i apologize. I have been doing research on BPD to better ubderstand it and I have a question. I understand that it is common for people with BPD to have a FP and I was wondering if when you have an FP it is common to mimic their behaviors. Not just their mannerisms but somehow getting medical issues they get. For example if your FP gets carsick somehow you also start to get carsick even though you never get carsick. Or another example your FP is lactose intolerant and suddenly you also become lactose intolerant. Is it possible or could it be linked to something other than BPD? 

Thank you very much for any future responses and if this is insensitive in any way please educate me!
