Accepting who we really are, more often than not, requires you to accept that you are different than everything you were told, growing up, was normal.
It means that you need to deal with changes to your whole life, most positive, some expected, but there are other, unknown things, unexpected changes and negative effects of this that can't be escaped.
Change alone is terrifying to most of us, human beings are creatures of habit, but change that has the potential to hurt us a lot, no matter how much good will come of it, is doubly so.
And so, we grin and bear it for as long as we can.
Cause it's less scary.
It isn't "easier" or "better", it's just known, controllable, something we already have and don't have to worry about any further, cause we know it and our place towards it.
People can become so accustomed to pain that they define themselves by it to some extent. It's the known, understood, and stable aspect of themselves and their lives. And in that situation, letting go of that pain can be almost impossible a task.
