Hope the LDN keeps helping you out.
I almost could've written that myself. My mom also had MS, and I was the secondary caregiver as a teen, helping out when my father needed me to. When they started the rumblings that this may be what I had - I almost lost it. Definitely not what I was prepared to hear. So understand that additional mind bending that happens on top of all else.
Venting is good for the soul, and glad you found us.
