If your gender and sexuality fluctuates frequently and randomly, and you never feel comfortable with a label for very long, I want to tell you that's okay, and you're still valid. You haven't failed as a queer person. You're just living your truth.
But it's one thing to just say that. What I would really like to do, is prove to you that this fluctuating nature of yours isn't abnormal at all, but in fact literally the most normal and fundamental thing in the universe.
In physics, there is this well-established, 100% confirmed branch of seemingly sci-fi gobbledygook called Quantum Mechanics. It is very weird, and complicated, and confusing, and it doesn't match reality on our scale at all. But at a fundamental level, this is what everything depends on just to be.
In quantum mechanics, it is known that the void is not entirely void. Quantum uncertainty still rules. All across the universe, everywhere you look, entire particles spontaneously come into being then annihilate each other before physics notices. Something from seemingly nothing. And this is because the void is in fact roiling with quantum energy, and stability doesn't exist. It's a myth. The void is always fluctuating randomly, in 100% unpredictable ways. It is always changing.
So on a fundamental level, change is the most normal thing there is.
Is that not good enough for you?
Then let's look at time. Time is change. If something isn't changing, time has stopped or no longer exists. Nothing is constant, nothing. Even radioactive waste has a lifetime and will eventually change into inert, safe materials over a long enough time. Everything changes, always, forever.
Change is the nature of all existence. It is normal, natural, acceptable, and necessary for being human. A human who does not change stagnates and gets left behind, often stuck with bigoted unchanging views.
But look at you. You're not like that at all. You are change personified. Your sexuality isn't weird, and there's nothing wrong with you.
You are just an expression of the nature of the universe. You are what it is to be human. And I think that's Pretty Damn Cool.
