Insonmia, afraid of having depression

Insomnia for several months, the longest more than 30 hours did not sleep, these months either a whole day did not sleep, or sleep a while, half an hour or 1-2 hours to wake up, and then can’t sleep back, or very sleepy, the longest 16 hours.
Sensitive to sound, a little sound, let me very fidgety, temper, heart speed, inexplicable unease,
From the past, I have the feeling of wanting to die, and I feel that life is meaningless. I care too much about what others say, and a careless word from others, which makes me struggle for a long time. Because of this, I feel uneasy and think a lot about myself.
Can’t get motivated to do anything, get angry easily, get irritated at the slightest thing
Poor memory, the next second I forget what someone said, general forgetfulness, difficulty concentrating

what should I do? should I go to hospital?
