First Light. I am on SR because my 23 year old son struggles with addiction.
I wanted to say that as you find a way to detach for yourself I would suggest that you look at the recovery support you provided for your daughter more positively. You provided her with the opportunity to learn how to be sober and how to support her own sobriety. You saw positive results and her ability to develop confidence. Those are tools she now has at her disposal should she make different choices in the future. You did not waste anything by helping her; now you can relax because she knows what she needs to do if she decides.
Now you can spend your money, time and travel supporting yourself as you find your balance.
