Moving Too Quick / Difficulty Sleeping

Time moves a bit too quick, I have no time to take a deep breath and grasp sense out of things. Instead, I have to act quickly and most of the time "irrationally" and face the consequences that are to follow. A year ago seemed just like yesterday, when I decided to meet up with the most lovely person in the world. I have missed those days, yet somewhere in my brain, it makes me want to move forward. These conflicting thoughts are giving me headaches everyday and preventing me from sleeping. To be quite honest, the last time I really have slept a good 6 to 7 hours was back in early April. Ever since then it has been only one to two hours, sometimes even just 30 minutes. I have no idea what is the cause and I feel no physical stress, but I know there is something back in my brain that is bothering me but is refusing to reveal itself.
