I got a diagnosis when I was in college (inattentive type, definitely not hyperactive). It was a bit of a rollercoaster for me.
I also have anxiety and disthymeia, so meds were complicated. Stimulants send my anxiety out of control. Ultimately, I'm unmedicated for the ADHD, now.
It's been 20 years, and I'll admit, I fear any major med changes, because it can be ~1 year to get it all worked out.
I would say, make sure you are working with a psychiatrist who specializes in ADHD and a psychologist who will partner with them to aid your treatment. Their experience is key and can save you a lot of time struggling with meds, I wish I did that from day 1. I originally started with a PCP and then psychologist + PCP and really struggled from bad treatment advice.
I was "smart enough" for it to not seriously impact me until later in college. I would dive into 1 class and neglect the rest.
But my career is pretty tolerant of it. In some ways it is an asset. I have developed a ton of coping mechanisms to compensate, and have also learned to build in time to let myself go. It took me a while time to "forgive myself" for needing that, but a good therapist who also had ADHD helped me.
Taking sensory breaks is really important for me. Shifting to working from home meant I had to learn when I should take breaks from notification overload. I only allow my calendar to notify me then. I do benefit from working with people who really know me and help support.
I also cannot track time internally (I do not know if that is common or not). So making sure to schedule things like lunch has been important. It's easy for me to get lost.
My wife is also amazingly supportive. We complement each other very well and have for years. We are very communicative and that has helped a lot.
I'm sad that my one of my daughters is struggling is struggling with it early in school. School in general is just so incompatible. I can sympathize in many ways with the "inattentive" aspects, but she is also hyperactive which is foreign to me.
