Kudos to you for not buying into labels easily.
In your own self interest & future well being, if you want this thing (uncertainty, doubt) out of your life
forever, why not get an independent 2nd, 3rd ... opinion?
However, in the event that it
is BPD, then
the truth would set you FREE! You cannot correct an issue if you are being treated for an entirely different one.
In the end, only you would lose.
Get other opinions to make sure. This is about YOU - not them.
Again, kudos for not
mindlessly accepting a diagnosis - too many people do. And the fact is, medical professionals make mistakes too.
Good luck
