Needing Closure

Hello everyone. I really don't know how to proceed in telling my story or for asking for help. But there's an aching feeling in my gut, about my identity, my circumstances, and how I react to both. I've tried talking to my parents, wondering if I were adopted. My dad's convinced that I am not. My mom however, seems to know more about it than anyone else, but yet refrains from giving me any closure. The connection to my parents is not as weighty as my brothers with them. I mean, I understand them, but it feels like their values, traditions, and skills do not resonate with me. And I have an idea of who i think my real mother is. There are many moments in my life, where I was connecting with my aunt more than my own mother. When I would cry and cry, my aunt would be the only one to calm me down when i was a baby. This I heard from the whole family that witnessed it. And my memories and what I remember feeling when we were around each other, my mom, my aunt, and myself. I was little, and I was in the backseat of the car, and I remember hearing my mom arguing with my aunt, and heard, "There's no way you're ever going to take him back, and that's the only truth you're going to care about." Later on when I was eleven, I remember going to my aunts house by a lake, and she offered me that I should stay with her. She didn't offer that to my brother. And I refused, because my mom made her out to be crazy. I haven't had the heart or courage to approach my aunt about it. Afraid of the consequences. But every time i reflect on my life, i can't help but feel there's something missing. Like I've lost something I've never had.
