@defleurs I've been a member of Al-Anon for decades. This is a support group for people who love someone who has problems with alcohol, drugs, etc. One of the best things I learned is to write down whatever it is that is troubling me and put it in my "God Box". I am physically turning over my problem/fear to God. This small action has given me so much relief over the years as I believe that I will receive what is needed at the appropriate time. I think that journaling is like this, writing it out somehow reduces the magnitude of the fear/anxiety. I journal too. Sometimes I look back and see that what I thought was a huge problem has resolved itself without any help from me!
Also I think you are wise to review your financial situation and documents with a fiduciary financial planner and to take your daughter along. I recently changes my Durable Power of Attorney for Healthcare and Finances( two separate documents) and my will as these all had my husband as the decision maker for me. If you have a joint revokable trust you may want to look at that as well. I recently learned from our estate attorney that I cannot make any changes to the trust that she recommended unilaterally as it is both our names and my husband is now not mentally competent to approve any changes. Best of luck with everything you now have to deal with.
