It sounds like you would benefit from a "to do list". It can be as simple as a text document on your computer or a post it note with some things you need/want to do written on it. You can make it more intricate with a planner or software on your phone. It doesn't matter which way you do it as long as you don't forget to look at it.

Write different tasks (laundry, vacuum, exercise, visit Jeff, watch Frasier, etc) in the form of a list and get them done during the day. Those tasks that you do not complete go on the list the next day. This will give you more productivity at home and away from work, so you get more stuff done in less time and likely feel better. If you wish to go further, you can assign a letter (A, B, or C) to each task representing the priority of each. In this example, A would be more important/urgent so you would try to do A tasks first.

A to do list is a simple option that I think would help you. It can literally be made in seconds but it's not the only option. I would also consider a new hobby, for example. Whatever you decide to do, good luck.
