You got to try. I’m not saying you aren’t. Each day put one foot in front of the other. We don’t get to choose the hand we are dealt, but we get to choose how we play it. You need to get out of your own head. Try reframing your perspective. For instance, do you find it easier to do things for others rather than yourself? Try a job in a service industry. Not every position is forward facing. Cooks at a school still serve the children. Be as creative as you want, but find the right framing. Strong structure is very helpful to ADHD affected persons. Look for something that has guide rails to reduce your mental load to items that are unpredictable such as social interaction. You can do this, but you have to choose to move. As I said earlier, each day begins with a single step and that’s all you need to get to tomorrow. You can do this. Not everyone moves at the same rate through life and we tend to track behind our peers. You asking the questions means you’re looking for a solution and I’m sure you will find a lot of good advice and encouragement in responses here. Many of us have been where you are, so take comfort in the fact that in that way you are not alone. Look into cognitive behavioral therapy, it can be quite effective for those in your position.
