I think this is the beginnings of eventually dealing with and improving upon your self worth. Listing off things you do want will give the therapist a pretty good idea of where things presently stand in that regard.

Look, even writing down "I don't know where to start" would be helpful as it indicates to the therapist the extent of the difficulties. Remember too, you aren't the first person to experience these difficulties and find this homework overwhelming. That might be a good place to start even, "I don't want this to be overwhelming. I want to feel good about starting this."

What if you were to think about your daily routine and his? Perhaps jot down for yourself your feelings about each incremental part of the day noting what time and experience is a trigger or gets under your skin. Note too your recation to it and how it changes your mood. This might make things easier to then address that homework.
