I am trapped in a spiral of misery

every day is the same, I am tired, I feel like I'm going insane, I dont want to live, I have responsibilities but I can't deal with them, I can't deal with myself, I am not eating nor drinking water, I am pulling all nighters every day, everyone is mad at me

I am trapped in a spiral I can't get out of. Is there a reason for me to keep going if things will only be worse?
