I am so sorry to hear of the death of your mom. I also lost my mom to the dreaded cancer & then a few years later lost my brother to AIDS. I know how hard it is to lose people so close to you. Please do not feel guilt over not being there. You were there when she needed you most during her life. If she could tell you herself I am sure she would say it was ok. As my mom said she wanted people to remember her the way she was in life. Her favorite saying was send me flowers while I can enjoy them not when I pass on. Please know we as your extended family are here for you no matter what. I wish I could help you with this doctor but do not know much about him. Good lcuk in your search for the answers.
Hugs-prayers & pain free moments to you.
