I also have ADHD but you really have a different case with me. I diagnosed with ADHD when I was 23 years old. I really have a hard time focusing on my job. I started on a specific task then I will move to my next task without finishing the other one. And, I'm having a difficulty overcoming with ADHD. I don't want to quit with my job so what I did is that I undergo with medication and I'm planning to have a therapy.

In your case, I think it not just about ADHD, If you really are confused you can seek help with the experts,
