this is the same feeling i have and this is what has driven me to get clinically tested for adhd over the last 18 months i have cut out every possible source of distraction - no social media no youtube except for tutorials moved away from roommates keeping a distance from small-thought thinkers and i started learning new tech for building things on my own guess what some 20 courses across 7 different subjects and today i know nothing and am clueless about what i should do next or even what i should be doing right now  what adds to this hopelessness is that no one understands what i am trying to do my dad simply doesnt believe that i genuinely want to do something and that im trying hard he has seen me as a mediocre student throughout school and college and he thinks thats what i am ive never been able to put this out so clearly - i want to do it and i spend a lot of time sitting down to do it it is just that i start thinking something else in a couple of minutes and i am not able to control this wandering of thoughts how much ever i try  i am 28 now and much dumber friends at school and college have all gone on to do good work and here i am still going to do and nothing done
