Looking ahead can be stressful. So, for now, don't do it. I found that when I felt "ok" and I looked ahead and started worrying about when I would not feel "ok" then I stopped being okay in the moment. It's work to stay in the present but if you are "good" in the present then focus on that.

It's okay to be scared and unsure. You are embarking on something that is totally new. It's natural to have intrepidations!

Why not make a game of cleaning house with your son? Do races to pick up toys or something fun (as fun as cleaning can be, lol!).
