Happy dance time!!
Take a deep breathe and realize that you will be doing this so that you can be there for them as the grow.... instead of being at home and in bed.
Try not to look at the whole treatment at once(other than when it's a must), but try only looking at it one step at a time. First things first, and that means you getting to this appt.
Then you need to wean your precious babies so that you can be well again.
One step at a time, one day at a time.
