Hi Nike, I can relate to what you have said. The urge to clean, imo, is our mind's attempt to establish control on things. Since you had missed school and spent time on a movie, may be unconsciously you wanted to take charge of things again and the easiest way to do that is to start cleaning.

As for not being able to finish one thing and starting another, this is the struggle of a perfectionist which (imo again), is amongst the causes for depression. I think you are trying to arrange/clean everything perfectly but then there are no perfections in real life, so you end up quitting on one thing and then start another.

Unfortunately, I can only try to analyse the situation based on my own experience and understanding but I don't have much advice on how to cope with it.
