things tt keep me awake at night

1.overactive brain from overworking in the day
2.the dark
3.memories of grandma & missing her
4.the guilt of not being by her bedside when she died and when she was laid to rest in the coffin
5.fear of not being able to finish studying
6.fear of not waking up in time and not at all
7.work and the thought of it

i can't keep staring at my ceiling or into space till the wee hours of the morning. i need sleeping pills.
