Sleepless

Recently, I cannot sleep early at night while other go to sleep,; often being awake tilluntil the sunrise and then, I fall asleep. And during the time, at dawn, some thoughts come over to my head. I must say they are it is neither important nor clear, though it is obvious that every thoughts are is related to regrets.

Very nice writing, I like this a lot! The sentence that starts "And during..." would be called wrong by a school teacher because it starts with a conjunction but it is commonly acceptable, especially in poetic writing.
