Why do rhythmic noises cause me to not be able to sleep, and how can i avoid this?

birds singing (the current situation), snoring, loud breathing, air conditioner whistling, someone shoveling leaves off cement (cough my neighbor cough), cd drive in my boyfriends computer continuously reloading itself….basically anything that is rhythmic and repetitive causes me to not be able to sleep. and essentially, one of these things is happening every time i try to sleep. it’s getting old, i’m sick of laying awake thrashing because there is a bird singing outside my window.

i cant sleep with music on because my boyfriend cant sleep with music playing so…there’s that.

this sometimes becomes a serious problem, especially when i have PMS and everything really fucking pisses me off.

but why? why is this such a problem for me? HOW DO I SOLVE IT? i really like to sleep. and right now…i really need to sleep. but this bird…....is it hopeless?
