Is there something in my genes that is making me feel more sensitive to rejection? Is it possible that I actually feel more hurt when I'm ghosted than other people... and that there is a biological basis?

My whole life I have cried more than my friends, gone mental on romantic partners who took too long to text me back, and generally felt like the world was a bag of knives just waiting to jab me at every turn. I then found out that one of my genes may be responsible for some of these feelings... so I tested myself.
