(((( sister ))))

I'm sorry you're feeling overwhelmed with all that's going on. I'm glad T called you back and you got to talk to him. Could you call and say that you've thought more about it and would definitely like an extra appointment. Maybe he was so intent on listening to you in that very moment that he was not thinking of the possibility of an additional session....

Your son can understand that you need extra time for you right now and you can tell him how involved you need to be with your practicum work this weekend. Take him out to rent a bunch of movies for him to watch this weekend, have him order a pizza, bake some cookies for him to munch on and let those things stand in for you while you take the uninterrupted time for you that you need and deserve.

Don't forget your relaxation / visualizations! Maybe this is the time for some extras?

Be sweet and kind to you!
