'Holy shit! Becca! How'd you get ou

'Holy shit! Becca! How'd you get out?' Mitch sprints to the front door, leaping over the couch on his way, and scoops her off the floor."
It hurt, realizing just how much these lines reminded me of the day when someone I loved/love said "holy shit!" when he saw that one girl and then he walked to her, gave her a hug like I wasn't even there. I still remember the look on his face when he saw her. The look I'd probably never get.
There were so many things happened last year that are still haunting me. The worst part is I can never get the girl out of my life. If anyone has a way to get rid of nightmares or how to deal with them, your advice will be more than welcome. Help me.
