I just love your gumby avatar... made me smile. Thank you.
I wonder if there are things that might make you feel less stressed while you are there. Might you take things that might make you feel more at home... a comforter, pictures, etc..? Might you also have a cell phone or something that will help you feel connected with others that might comfort you? How would you envision a successful weekend and what would that include? Relaxation music might make you feel in a place that would be more comfortable? Headphones... What will work for you?
Also, I hope that you will have a good weekend and successful. Think of how much this means to your daughter. Know that while you are in treatment (and beyond... ) things will progress and if things do not always go the best that you celebrate and acknowledge the things that might be going well and what might be done better the next time.
I went to a day long seminar to a wonderful gentleman that was teaching about how to break horses and how that interlocked with people relating to others. The most beautiful thing that I got from that beautiful day ... was... PREPARE YOURSELF FOR SUCCESS. I think that you have started that by starting this post. Good for you. Continue to think of what for you will help make this successful. What do you depend on and what will make it easier for you?
Also, work to let yourself off the hook. Do what you need to do but if it does not go as smoothly as you might dream... do not fault yourself.
One foot in front of the next..... and ... This too shall pass.
Bestest wishes... Practice self hugs ....
