I Can't Sleep When I Have Too Much On My Mind

I go to bed so late many nights i don't even know when because i turn my clock away. i over think things and i can not stop thinking, another reason i go to bed late is i hate silence, especially the time period when my thoughts stop for a second i hate it being silent. so i turn off electronics late or i listen to music but i can not fall asleep listening to music or watching a movie.
