Morgan,
You are an amazing person! I am truly blown away by what you and your family have accomplished. It will be difficult. It will feel weird, at least for a while. Just remember, do it a day at a time. That's all you have to do.
A family is a microcosm. When one member changes, even a little, the entire family changes. But usually it takes a little while for the changes to become apparent. They don't happen overnight. You might be feeling a whole lot of different emotions inside of you but when you look at your other family members, you see them doing the same old things. Chances are, they are feeling different feelings but don't really know how to act on them yet. So things appear to be the same as usual. It's ok. Try to stay calm. Deal with how you are feeling and don't worry so much about them. As you change, the family really will follow, trust me. But it does take time. I know that a lot of what you were dealing with was because of how your family operated. Have faith that your therapy will help.
We care.
