I do my homework and I get like this X__X
lol. I'm not exactly sure about how I fall asleep. Like you, when I have something on my mind I have trouble sleeping, but that only depends on
what I am thinking about. So try thinking about something you like and create a fictional novel in your head. Usually, my stories are about me becoming a famous singer/actor/basketball/football star and marrying the current female celebrity I had a crush on. I would think about the house and how everything would be set up. I think of my children, my dog, my friends, etc. Eventually it would become too perfect so I would think about a situation where I or my wife would be
unfaithful and drama arises. AND if you think about all this, chances are you might be asleep before you know it! At least thats what I do... I usually have to skip my mind to the drama where me or my spouse gets caught cheating on one another, because I hate falling asleep before I get to the good parts! LMAO
The main thing is: Don't think about anything that's bothering you or actually, don't think about anything that is REAL.
I actually tried counting sheep in my head once too. It works too to my surprise!
