Doubts about my diagnosis

Okay so a couple of years ago I got diagnosed with bl2 when originally I thought I was just going for an ADHD diagnosis. I have been consistently taking my meds of Wellbutrin and latuda for the past 3 years. However I have been dealing with a lot of executive dysfunction and motivation skills and I'm getting a second diagnosis just so that if it's possible that I have ADHD or I just have both. I hope this makes sense. Am I going about this the right way?
