Anxiety as a driving force isn’t really great for your health, so I would be happy to be rid of it. You should look into treating the ADHD itself, could be with a medical professional and trying if there are meds that work for you. One of my kids also has ADHD and we did find some meds for her that help after going through a few options.
You could also try controlling it yourself, this is a bit of mixed bag though and I would recommend exploring the medical options if they’re available for you.
For example, I’m quite a bit older than you and I never got it formally diagnosed, so no meds. I try to keep work and free time as separate as possible. For example during work hours my personal PC is strictly off, I do my work with another PC that only has access to my music and what is required for work, no other media that could distract me. I need to always do something, so basically the work gets done because I don’t have anything else to do. I don’t always stay on the right task, but this works well enough for me.
People and ADHD are both on a wide spectrum, so it’s always a bit of trial and error to find out what works for you
