huge problem for me as well   i am working on just focusing on one task at a time - i know something like doing the dishes wont take 2 hours so i will just focus on completing that task sometimes i have to organize the sink then take a break then get back to it later so it is not always successful but i am finding the less i focus on the time and just look at one task it is getting a little easier to accomplish something   somedays that momentum will keep going for multiple tasks and other days i dont complete the one task perseverance is how we try to get the other side of these off-putting feelings   and dont beat yourself up if you are not successful if i didnt complete a task i just try again tomorrow   but i definitely understand how friggen frustrating this feeling is ugh
