So now I have Saturday for myself with no plans so far and Sunday plans don’t work out,
If nothing pans out Saturday, go out and pamper yourself (facial, nails, massage). You will be surprised how much better you feel after. Also, go buy a good book (The art of not giving a [censored] is an excellent read) and sit in a coffee shop. It will seem weird at first, but it gets you out of the house. The emptiness is overwhelming the first few times the kids are away, but eventually, you will learn to love the quietness of it and the fact that you can do whatever the [censored] you like (stay in your PJs and watch rubbish telly, dance around the kitchen in your underpants, whatever). The time is yours and no-one is going to tell you how to spend it.
