Am i in love or what!?!?

There is this certain girl at school. She is so pretty. I met her at grade 2 and had a crush on her since then. I didn't understand love or anything but I knew I had a crush on her. Now I am on summer vacation after 5th grade and I feel hollow inside. Like I had a piece of me somewhere and it brings me a hollow feeling without it. Then I thought "Maybe this thing I lost just got lost now, and I had it before! Let me think to the best moments in my life...". Then I thought about every happy moment I had from as long as I remember, and that was when I was 3 years old. It took me about half an hour to reach the time I first held my crushes hand and thought "Is this it? Is it this girl?" Then I thought even farther to when I saw her face at the beggining of the 4th grade and remembered how I felt every feeling in the world mixed up and the feeling I was punched in the stomach, but no ones fist was in my gut. I also remembered when she looked at me and said hi, I raised my hand and replied a hello but after that I couldn't move! It was like the sight of her got me distracted from some hands that came out of nowhere and held me in my position. After that I got to some thinking, and I thought for a few hours and thought that other people could help me! And so there it is, I found this site and posted this story, I hope you people know what you're saying, comment about what you think and I'd prefer people who had similar things that happened to them.
