I agree with shattered. Depression and anxiety can cause a person to lose interest and motivation while you don't necessarily feel "down" at the same time. I have been in the same situation of feeling apathetic about taking care of regular tasks and chores. I often wait until the need to do certain tasks becomes critical.

For me, it's a combination of lack of energy and a feeling of being overwhelmed. Sometimes it helps if I can find the motivation to make a list of what needs to be done, and then try to focus on just doing one or two of them each day (skip a day if needed in order to be gentle with yourself).

Good luck to you, and just remember to be kind to yourself
