Why do I wake up thinking about incomplete work?

Stress. If the pressure at work or the amount of work for studying is too much this creates an unprecedented thought process in line with stress. It could be an overload of work, doubt in ones capability, trying too hard to be perfect, living up to other expectation or just not believing in oneself.

It sounds like you are under a lot of stress and pressure trying to get things done and it is natural that these things will be on your mind a lot. Try to take time to relax and organise everything, maybe you are feeling that you aren't going to get everything done in time.

Our mind keeps learning our moves even though we are not aware of it. Sometimes we find ourselves wandering off into some thought but still we walk our way back to home by the usual route. The more organized person you are, the more likely such alerts. So it is basically your mind acting like a to-do list or remainder. Some people need to train their minds for this to enhance their focusing and concentration. So this is basically a healthy mind at work. But if you think it stresses you, then remember it is just a sweet reminder of the beautiful mind of an organized person (you of course) at work.

It's your brain working on over drive, constantly thinking of how to resolve problems; maybe before you sleep you need to do some kind of relaxation exercises to clear your mind

It looks like the problem occurs from a sense of guilty. You can focus on what you will do on the next day to get things done. If despite your efforts it still remains incomplete, then it is probably very human and no needs to worry about it. Sometimes we tend to compare our ability to others' but becoming better person than our previous Self is the best achievement of all.

Its basic human tendency to think about tasks which have to be completed because these are causes of stress. It would be a good idea to schedule things to be done so that you don't burn yourself out thinking of all possible outcomes of what would happen if the work isn't completed.. Remember, you are not alone in feeling this way.. Most people wake up thinking the same thing.

I know how you feel. Are you constantly stressed out about the amount of work that you have to do every single day? It may just be that you are overwhelmed, burnt out, or simply unmotivated. It looks like it's time that you give yourself a mental break from your work so that you feel fresher and more productive the next time that you return to it.

Know that work will never end, there is always gonna be incomplete work which u will need to do and its always asap. Just manage your time and task well and don't stress about finishing it because work never finishes.

This sounds like you are feeling a bit stressed/anxious. It could be because you are taking on too much work, or perhaps you are worried about your performance at work/school. There are a lot of possible reasons, but only you know for sure, as you know yourself best.

It might help to finish each day's work promptly so that nothing carries forward to tomorrow . That can add a lot of pressure.

It sounds like incomplete work has been stressing you out so much to the point that you can't rest fruitfully without being bombarded with anxious thoughts of completing it. Don't worry, it's normal and happens to everybody at least once in life!
