Realization may be great for the relief of the great existential questions and internal stress, but it may not relieve the issues you have with other people, especially those close to you that depend on you. Although realization changes your perspective, it does not change theirs. This fact alone may create issues, especially with ones closest to you.
When the great "Who am I" question is answered, much of relative life and its pursuits lose their meaning. Motivation regarding such goals drop like extra baggage. They are no longer required for your happiness, but those around you, not experiencing the great relief, may find your lack of motivation to be a disaster, a loss of what it takes to make life worth living: chasing experience, getting things done, getting things, the pursuit of happiness.
When you have a sense of completeness, of wholeness, and any moment is as good as the next, where is the motivation for the pursuit of anything? You are no longer looking for "new and different." Now is good enough. The moment you are having is perfect as it is. You don't ask "What's next?"
While this is wonderful for you, those who have depended on you to share their pursuits will find you lacking, may find you lazy, no fun anymore. When you have lost the wanting of more things, a bigger house, a newer car, more money, you are no longer on their team. They may turn on you, not understanding where their partner in pursuit of things got lost.
How do you explain to someone you are already complete? That there is nothing more you need to do to feel okay? This perspective is yours, not theirs, and unless they realize, they will not understand. You may be told you are no longer helpful, understanding, or living in the real world. Try telling them the world they are in is a zero sum game and you're not in it. It doesn't go over well.
Others will not understand what happened to you. They will feel they have lost you. They have, but how do you tell them that you also lost yourself? How do you tell them you are no longer the personal so and so, but are the impersonal Self?
There is a moral hazard to realization. You may have found peace, but those around you may find you frustrating, indifferent, unattached. And you are.
