Can't sleep

I'm wondering if I have insomnia. I've been staying awake on my bed for hours. I've tried many online recommendation to get to sleep such as get rid of the phone, take a deep and periodic breath... However, every time I closed my eyes, trying to find inner peace where I can become calm and relaxed, my heart continuously get aroused. I don't know what disturbed my calmness, maybe it was the aftermath of my recent broke-up...I didn't know what to do, I can feel the emptiness of my heart and I felt that I've lost direction of my future, at least tomorrow. I'm doing college, I'm going to study abroad in USA, I'm going to pursue my dream and become an engineer...My goals and my spirit. It is 2.02 midnight, most of the people have already gotten to sleep, charging themselves to overcome the problems they have expected, the obstacles which will make them grow and become stronger. I wish I will fall asleep very soon and wake up tomorrow Morning fully-energized to work as hard as the enthusiast and the dreamer. I console myself I will be on the correct track, which will ultimately lead me to my goals.
