I dont know what im doing

it just seems like nothing is real anymore, im not looking forward to do anything, i dont see myself in the future, and dont feel anything, the thought of killing myself goes trhough my head every day, nothing seems to have importance nothing seems to have meaning and i cant do anything because i dont care about anything anymore. I just go outside go trhough the day and suddenly im back in where i started, its like im just existing in automatic. the only thing i enjoy is sleeping cause it makes me feel like im not alive anymore
