I absolutely wish Backie all the best. I understand how frustrating and disabling FND can be as I have it myself. You really never know how a day will turn out. As for making plans... forget it !
It can affect you in many different ways from exhaustion to pain, from falling over to depression, from speech to balance.
On my "worst" day it looks like I'm having a stroke. Speech, co ordination, brain fog and my legs forget that they're supposed to hold me up.
In my case I try to be optimistic and friends and family support you once they understand how it can affect you day to day.
All the best, Backie.
