My wife's mom told her that BPD is made up and to stop taking her meds, stop going to the doctor , and just grow up. How did we deal with her? The same way one would deal with a person who thinks the world is flat or Howard the Duck was a good movie: we ignore her and do what is best for my wife and her health.

Your mom may be ignorant about this illness, in which case she needs educated. It could also be she is afraid to acknowledge it because she would feel guilty about "giving" it to you. Our son is BPD2 like my wife, and she has horrible guilt over passing it on to him, though we had no control over it and no idea she even had it until he was 4.

Either way, do not let it interfere with your health. You have several professionals who say you are bipolar, and in this case mother does not know best.
