Yes I grew out of it too when I realised that the Universe wasn't rotating around me and that everything that happened wasn't all part of some grand plan aimed at me specifically.
My Mum never did though, every word everybody said was analyzed, every phone call was investigated for motive, every gift horse dentally inspected. Every eye in the shopping Mall was inspecting her for perfection, any laughter was questioned for personal relevance to her. She was still a 13 year old neurotic narcissist at 91.
It's a hell of a way to live! Grow out of it, fast as you can. Not giving a toss has a lot more going for it.
