My T shared with me that as I got/get better I wouldn't "need" the same fantasies/symptoms, interests, etc. and they'd go away but that other things would take their place and while it would be sad and I'd miss them, it would be moving on and other things would replace them so I wouldn't really "want" them, just the memory of them.

Think about when you're a kid and have things you love and think you'll never let go of and you outgrow them. I'm still trying to figure out what happened to running into the water right when you get to the beach :-) I thought the adults were crazy to want to lay on the sand instead.
