What you said and your statement that “it’s a bit like grief” are dead on. I wasn’t kicked out by my parents, but I lost my dad when I was 27. I’m 40 now and still miss him but the feeling dwindles with time. I’ll always miss him but the impact of that feeling will always lessen as I gain more experiences. I suppose the same is true for any trauma of a similar magnitude. I imagine there are traumas that surpass the loss of parents in magnitude, though, and some of those may not pass in the same way.
