hey brother,    it's all good.  let me tell you why.  your brain has just undergone seemingly traumatic stress- for lack of a better medium to capture the essence of your experience- to which i feel i can relate.  it has done something to adapt to that stress, but as you were not fully conscious during the experience, you have difficulty integrating the factors of change, then change itself, and in turn- the end result, which is how you currently feel.  your brain has made a quantum leap, and although it may not be in the direction that you thought you sought and have been seeking- it has adapted to your stress and evolved accordingly.  your after effects were affected by your body's interpretation of  the message you gave it when you enacted physical sensory overload, and in-turn overload of conscious awareness.  It will only take a little while for your mind and body to find another sync that flows accordingly.     you feel worried that you will not be the same...yet do you truly want to be the same person...i guess just be careful what you wish for, because it helps construct the percpetion of your reality.  also, psychedelics are not like beer- after you've had one too many, the results are not exactly predictable.    you've changed very much indeed, but intrinsically you will always be you- regardless of where you are now, where you;ve been, or where you'll go- a whole within a whole- ad infinitem.    imho, you are brave; but bravery does not guarantee glory.  take this battle scar, and from it put forth new light and life.    p.s. great tek 8)
