Fears from A Traumatic Experience in Childhood

When I was around 6, my family moved. I can't remember exactly how long the move was but in my mind, for at least 2 weeks, in the evenings, my mom and dad would put me to bed and leave to go move more furniture after they thought I fell asleep. But I hadn't fell asleep, because I was worried they would leave me by myself. And they did! I had never been left by myself before that point that I can remember. This process was extremely traumatic for me. Even after those nights, for the longest time, after going to bed, I would get up and peek my head into the living room to see if my mom was still there, watching TV. I was terrified of being abandoned.

Looking back, it was inappropriate of my parents to leave me by myself at that point. The 6 year old in me will always be a little sad, hurt, and worried, and justifiably so. As an adult, I carry these fears close to my heart and they manifest in my relationships where my fear of abandonment compels me to seek closeness and take any sign of decrease in closeness as a sign that I'm being abandoned. This is not justified. Knowing what I know now, I understand why I have been feeling this way, but I also now understand that it's unnecessary to feel this way. My partners have shown and proven to me time and again that even when they're not with me, they haven't abandoned me. They still think about me, they still care about me, they still love me. Next time, when my partner is not next to me, instead of jumping to the conclusion that they've deserted me, or they don't care about me, I will instead look objectively at past and present evidence of whether this was actually the case. And if there's any doubt that this (they've abandoned me) is the case, I will relax and not let my childhood fears engulf my adult self emotionally.
