I hate how people tell me there is nothing I am doing wrong in life when I am poor and suffering

People just blindly say everyone is doing well in life because they are stupid or lazy. I know I am not getting what I want in life. I am not satisfied. In high school, I I it got Bs and Cs despite studying intensely and using tutoring. I got cut from sports and got denied from the student newspaper and robotics team. In college, I still didn’t do too well academically and got denied from clubs. At 18, I picked up running as a hobby only to develop an injury that turned into arthritis. I can’t do any physical jobs now. I don’t have much left going for me
