It's ok that you did not get out much today, Kathy. What you did was fine. Helping your daughter and doing your laundry is enough. And curling up and watching a movie sounds like a fun thing to do! You are spending time doing something your daughter wants to do. It's a bonding activity, something that will help your daughter feel closer to you. It's the small things that count, especially as a parent.
Your low iron levels probably explain some of your tiredness. It will be good to see how much of the low iron levels are affecting you and how much is your emotions once you have had the treatment.
Before you see your therapist, it might help to write down some words that describe how you feel. Get a pen and paper and see what words come to mind. Leave it and come back to it as you want. That way when you see her you can refer to your list to help you.
I hope it goes well tomorrow and you feel better. Sleep well, Kathy. I'll talk with you soon,
