Quality of life

Is a term that I'm sure most other people who are diagnosed with MS understand all too well.
I feel that it is an utter and complete lie. I am still plugging away,  trying to fix the problem,  and turn my self destructive immune system back to normal.
As we are discussing lies, why does my mind keep thinking about all of the lies and loss I've endured over the years, and in turn paints them to be truth.  I wish I could figure out what and why.
