I've been dxd twice too. Once at 17, I denied it, threw out the meds and carried on. 10 years later had a total breakdown, went into GP's office, put me on lithium set up Pdoc app. Go in to see Pdoc, BAM second dxd. That sort of solidified the deal for me. I took it pretty hard tho, my dad was also BP and we had a horrible relationship, so I took it as "I am just like my dad" which is of coarse not true.
