I cannot express my heartbreak for you and the loss of your precious daughter. I have 2 and a granddaughter. They are my life as well as my wife. I can’t help but feel a negligence on the part of the medical staff, in my opinion. Your daughter was off the opiates for awhile making her ‘opiate naive’. That amount of medication,dosage,etc. would definitely kill someone especially if there’s no home are staff or med staff around to monitor the situation.
Please accept my deepest and sincerest of sympathies and if you don’t mind, I’ll keep you in my prayers.
