Get a trust and put everything in it except your retirement plan. That includes your home, cars, investments, misc items, and have it done by a lawyer. Get a durable and medical power of attorney , a living will and a pour over will. You will be the trustee and you have to name a successor trustee to serve when you are no longer able to serve. The successor trustee can be a trusted, honest, wise relative, or a commercial trust company. Think about things that you have but don’t use nor need and consider giving stuff away to people who can use it. Once you have made arrangements you may feel that a burden has been lifted. I understand and I am still making arrangements although most things have now been decided. I am Gleason 9 CR, aggressive, incurable, locally advanced and 40 months since diagnosis. Had surgery and 12 months of ADT and Erleada. 78 years old. Good luck to you and all in our support group.
