I believe it's going to vary from person to person. I have ADHD, and BPD. Treating my anxiety is the most trickiest for me. The rest is easier, for me. If it was not for my technical job and constant classes I need to take to keep up, I would not even be concerned with my ADHD. But I do need to address that to keep my job. I imagine if I had a easier job I'd be fine. I can certainly see some one with ADHD having serious problems that could in turn trigger depression and anxiety too. This is what makes psychiatrists jobs so difficult, sorting out which came first and what's causing what and why. All we have to worry about is showing up to our appointments on time, which I hope you do next.
