ADHD refers to a spectrum of symptoms, it’s not necessarily a disease in itself. This is a very misunderstood concept, and I’m sure I will get pushback here on it because we get really used to our labels, but I’ve been through the system so many times and talked to a lot of doctors and have connected with the consensus. The DSM5, the manual from which we get all these terms and diagnosis talk, is always in a state of flux and is used as a guide for identifying symptom clusters and forming plans to ease harmful effects of those clusters, not labeling people’s identities or diseases, nor curing anything.
What’s all this have to do with your trouble focusing? That there is likely an underlying issue causing your ADHD symptoms, and this could be anything from an actual innate disorder like autism spectrum disorder, or it could be an effect of life experiences like PTSD from stress or abuse, or it could be your current lifestyle and living situation, it could be clinical anxiety/depression, or it could be something else entirely.
This is why the boring answer, which is most often the correct answer, is to consult an actual professional, not rely on asocial, sheltered, internet strangers because you will unconsciously seek out what you want to hear, not what you need to do to address the problem, which may in fact be something you really don’t want to hear.
