Never goes away. I'm 43. 1/2 way mark. Here's a pro-tip: Notice
  what age you compare yourself against. If you compare yourself
  "you at 15", you're damn old for 15. Compare yourself to 25, and
  you're a young 25. It helps. the answer for that for me has been
  pinning the fullness into the nowness. Now is about 6 seconds
  long or so. I have a service oriented personality - I like to be
  helpful. I get fulfillment in that. So, when I'm talking to
  someone I ask if I'm choosing the most effective words to convey
  to them that I understand, they're ok, and they're strong enough
  to handle whatever life throws at them.
  You are. Yet, you're also more than that. It's ok to play a role
  that isn't you because the real you isn't touched by the
  role.Some people believe your life is a story and you can change
  the words, change your character in order to be yourself. And
  that works.. to a point. But then you're also more than the
  roles you perform. You perform roles for others. You perform
  roles to yourself. Yet then there's the you without the role.
  It's there.
  Yeah definitely. I don't often mention God because that word
  sets off triggers in many people. My definition for God might
  not be theirs, and usually isn't. I don't even use the word to
  myself much and find other ways to say it. But yes, definitely.
  I wouldn't be here if it wasn't for everything that came before
  and I wasn't in control of any of the circumstances that led to
  my birth, and the fact that I'M STILL HERE is amazing. I could
  name 1000 reasons why I shouldn't exist. But I do. That part
  makes look around and go, HOLY SHIT, I'M HERE. a lot.
  *nice. I like that. If you feel the warmth of the inner hearth,
  the Hestia within you, you're never alone and you have a center.
    But yeah - the river. You're of it and in it, but not it yet
  it's also you. I could koan all day because this stuff makes
  sense to me. It is; and there's many roads. I feel bad for
  people in mystical-poor sytems because they really miss out of
  the good stuff. Oh socially yes. But on a personal introspective
  level, it's all yours. Oh yeah. heard about them. we had them
  int he 80s... the 90s, 00s, 10s... I don't care for systems that
  mentally abuse people psychologically... that includes the
  education system as it stands btw as one of the worst
  offenders... so I help when I can.
  Means everything's absurd. My mother loves an expression, "Man
  makes plans and God laughs". Also, there's the Platypus.
  I know the experience well. Are they jokes? Probably most likely
  yes they are. Start laughing at the absurdity of it. Imagine the
  look on your own face when you discover the irony and laugh like
  an outsider might but without feeling offended and instead
  laughing along.

  I have no idea of that will make sense smile emoticon
