From what I've read and observed, the meds take the "edge" off, but they don't lift the entire fog for the MLCer. They feel better and some of them can then sleep better and yes, they can function better....but mlcers are great w/compartmentalizing things, i.e., they can function in different areas w/o exhibiting a lot of depression symptoms. It's when they are alone or sometimes around us that they will drop their masks and show signs of depression, dead eyes, pale, sickly looking, sad, no spirit, etc.
They not only need meds, but professional assistance as well in order to navigate what they are going through. Some will eventually go see a therapist and others will continue to suffer all on their own.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
