So iv been diagnosed with BPD. I have a friend with ADHD and she thinks I have that instead of BPD.

Can both be diagnosed at the same time? How can I know for sure if I have ADHD? Common differences to tell them apart?

P.s I see a psychiatrist and she has only mentioned BPD but I'm worried she may have misdiagnosed or missed out the ADHD.

Any advice would be greatly appreciated! 😀
