second this. Time without other people's stuff in your stuff is invaluable. I would add that pomodoros can be really good for tracking how much you've gotten done, and then being able to walk away after a certain amount of time has been spent being productive. You may be getting more done than you realize - one of the factors of add is that once a task is complete, it flies the cognitive coop. I have this problem in spades. Also, it may be helpful to realize that if you're working on code, some of the work is finding the solution. Even if you don't have a scrap of working code to show for it, having done some work to find out what doesn't work or just reading documentation is productive work. Beware that imposter syndrome, it's a real doozie.
