Is it normal to see a girl so pretty and beautiful that it makes me cry?

I was watching a youtube video in bed, and the girl in the video was reading her favorite inspirational quotes, and not only was she unbelievably pretty and beautiful, but her personality was so genuine and real, her voice was so soft and gentle, and every time she touched her hair my heart skipped a beat, when she licked her lips my eyes were magnetically drawn to them, and whenever she moved her head to the right or left I found myself moving my head in the same direction and copying her expressions. When she said a little joke we both smiled at the same time. When a strand of hair fell on her face I stared for a second at how peaceful she looked and then a moment later I tried to slowly brush her hair to the side with my fingers. I even tried counting how many times she blinked. At the end of the video I closed my eyes and smiled and a tear rolled down my cheek because I knew I could never have her. Even though I only know her from youtube I think she is the most perfect and wonderful person I ever laid eyes on and she makes me feel something inside that I never want to let go of. I hear her voice in my head and I can't stop thinking about her.
