My private affair

Hello.

I find myself needing to write this out. It’s my first time truly "pouring my soul out" here, hoping to gain some perspective or advice from this community.
I will attempt to be concise and direct; I am available for any questions you may have.

I am 26 years old. I grew up in a small town with a fairly conservative upbringing. At 19, I moved out into my own apartment, primarily due to constant friction with my father and a desperate need for privacy.
Then, at 20, I discovered that the man I called my father wasn't actually my biological father. I had lived my entire life completely unaware. To be honest, the realization leaves a bitter taste in my mouth.
I feel as though I’ve been caught in a conspiracy orchestrated by those closest to me—especially my mother. It feels like everyone in my hometown knew the truth except for me.
I don't blame my mother—not consciously, anyway. I realize she likely carried the heaviest burden, but then again, shouldn't I have had the right to know who my father really was?
In the meantime, I have met my biological father, though no one back home knows about it.
It has become difficult to look my family in the eye. Even though I know they love me, I can't shake the feeling that I've been betrayed by their silence.
In a month, I have to move back in with them because I can no longer afford to rent on my own.
My primary question is this: how should I deal with this sense of "conspiracy" I'm feeling?
I struggle with a weak character and am quite dissatisfied with myself; I can see myself slowly morphing into the very man I am trying so hard not to become.

It’s a gut punch when you realize a whole chapter of your life was built on a lie—but it is what it is. There isn't much you can do to change the past right now. If they treated you well and actually showed you love, then maybe it wasn't all bad. They likely just wanted to protect you while you were growing up and thought keeping the truth quiet was for the best. Things will feel incredibly awkward at first, no doubt, but you'll adjust. Now that you've finally met your real father, he might become a steady presence—and as life throws more curveballs your way, this might eventually become less of a burden.
Living with a lie is exhausting, and honestly, you'll probably feel this nagging urge to confront them now that everything has changed. Whether or not you tell them you know the truth is entirely up to you—you'll have to figure out what's best for your own peace of mind.

Don't hold a grudge against them..
The fallout will eventually catch up with you..
They acted on what they believed was the best course of action, likely assuming you’d react like a child if they explained their reasoning..
Perhaps that would have been harder for you to stomach...

Try not to worry about the small-town gossip..
What matters is that you're standing tall and seeing things clearly...
Forgive them.. and let the weight slide off your shoulders.

Either cut them loose or give them a taste of their own medicine. Disgusting liars like that don't deserve anything less.

It's dry, it's dusty, the nights are long and cold. Your life feels like a wasteland, and you're terrified of getting older. You can hear the clock ticking like a sledgehammer hitting stone; just remember—you aren't in this by yourself, you aren't alone, you aren't alone. Come on! Can you hear it? Moby Dick. Get up right now and fight back; wipe those fake, plastic smiles off their faces. You crawled out of the ocean with a pulse that was slow and weak. You stood up on two legs, put on some clothes, and learned how to talk. And yet, you ended up discarded in a place they have the nerve to call "home." Remember this—you aren't alone, you aren't alone, you aren't alone. Come on! Can you hear it? Moby Dick. Get up and fight back; wipe those plastic smiles away. Why bother listening to these losers who still treat you like a damn child? Better find a different frequency; tune in to Moby Dick, the call of Moby Dick. They'll swear they love you, the same way a spider loves a fly. They promise you safety, but they won't even look you in the eye. Manipulated, regulated, crippled, and controlled—remember this: you aren't alone, you aren't alone, you aren't alone. Come on! Can you hear it? Moby Dick. Stand up and fight back and destroy those plastic smiles. Why listen to the losers who still treat you like a child? Just tune in to Moby Dick, the call of Moby Dick.
