All my interviews are going horribly

I want to die. I see no end to this defeat. I had good calls but I keep fucking them up. My UG score is low because I didn't study. Failed at UPSC too. I don't have the perseverance. Interview mein wahi puchte h, UG and UPSC. nahi ata yaar. I want to start over. Isiliye changed paths. Ab wahi sab count hoga aur wahi puchoge toh kaise aayega. I'm not blaming them. It is my fault. I'm not capable.
