It would technically apply for illusionary as well.
And, strangely, this feel precisely like what I had with a friend of mine. That is, after I couldn't "use" him like that anymore it really, really sucked. I had to basically relearn how to do things on my own, to kind of learn to live without him. It sounds kind of gay, but it's not. It was like a disabled person getting rid of their disability and then one day it coming back. Or somebody that suddenly got rich, got use to the big life and suddenly lost everything they had. Like a support has been kicked out from under you. It really, really sucks.
