There is nothing in the realm of human experience that should be in any way off putting to a psychotherapist
So, what you may want to start with is asking your parents to help you find a suitable professional with whom you can openly discuss this experience. I can assure you it has a very significant and important symbolic meaning to you and fulfills some otherwise unmet need. There is something quite magical in being a baby whose every need is attended to by loving, caring parents such that we need barely wimpier and, if hungry, we are fed, or if uncomfortable we are comforted. Its a bit like the idea of a garden of eden where all is provided and there are no responsibilities or worries. Then we begin to grow up, eating from the tree of knowledge, and are expelled from the garden to have to go out in the world and take care of ourselves. I mention this biblical story, not for theological reasons, but for the common psychological wish everyone has of being able to stay in the carefree place. Of course, all of the advantages of maturity would also have to be forfeited even if it were even possible to remain a small child. It isn't, thank goodness! the price paid would be much too great.
