Help

17, tried to change my life around since I was 14. Im at my lowest point, trying doesn’t work, nothing improves and I do everything wrong since im an idiot. All I do is fail and not do what im supposed to do before im actually able to achieve important achievements. Every day goes by like a minute, I’ve given up my hobbies, study routines that weren’t the best but atleast I was trying. After a health care I’ve completely let myself go. I don’t know what to do anymore, my grades are going to go down soon, no idea what to do after graduation, I’m scared. It feels like the hours of the day are never enough and that im constantly living in the past, its going so fast I already picture myself as my life is finished. Someone please, just say something to me that can help or what you’ve been through, I’ve written constant posts and get basically zero attention. I want to fix all of this by myself but I can’t. If basic instructions or tasks are hard for me to follow, then why was I born like this?
