How can I sleep without my mind thinking of a million things?

Every night when I go to bed, it takes me an hour to fall asleep because there are so many random thoughts running through my head,

and then when I wake up in the middle of the night to use the restroom and go back to bed, it takes me a while to fall back asleep sometimes again because of so many random thoughts going through my head! I have tried all the tricks in the book to stop it but nothing works.

I have tried meditation (really), I have tried counting, I have tried focusing on one image since a lot of our thoughts come from images, I have tried focusing on one in particular boring thing like my toe!, my mind is just to powerful! help please! thank you.

p.s. I am 19 and am a male if this matters.
