Oh my sweet Valentine!! help please....?

I think this Valentines day was life changing for me!

This was the situation:

When we and my friend were talking,my other friend called me and said that someone wanted to see me.

Without no hesitation,I went to see who it was.

I was so surprised to see that the students of the class where my crush was sitting at a table near our canteen.I already knew that my crush was there so I was shy.

Then,some of the girls of that class and my friend started teasing me and they ask me if I have a gift that I was going to give to my crush.

Then,my friend started pushing me closer to her and I have no choice but to give to her my gift.

So,I went to the table where she sits together with her friends and seated right next to her.Then suddenly,her friends ran and left us two together.Both of us were shy to look at each other.

We were so shy that moment because many students were watching us.We both stood up and I was planning to go back to our room and I guess that was her plan too.But My friend started pushing me back until I realized that we bump each other because her friend were pushing her too.Well,I had no choice but to gave it to her so I did,and she said thank you to me with her sincere smile.

*The end

Now my problem is,ever since that incident,I was obsessed over her.I couldn't help but look at her pics every minute,and I think I'm going to die if I can't tet her or pm her.

Why am I acting like this?

help please?

What shall I do?
