I'm sorry you're going thru all of this! Prayers for healing! I strongly suggest taking one or two other people with you, family or friends, to help listen, understand and raise questions!! I totally understand the brain fog! It is hard to take in all that the doctors say, so having someone with you to help take notes and ask questions has helped me!! Don't be afraid to ask them to simplify and speak in "english" until you are comfortable with the plan and understand your options!
Prayers for healing and success on the rest of your journey
