If you're ever having these feelings of loneliness or ineptitude. Reach out and talk to someone. It doesn't have to be about anything at all, but try to keep connections open to loved ones. If you don't have anyone to talk to, write it down, but it's very difficult to fix this on your own. Mental health is difficult and it's almost impossible to get a new psychiatrist/psychologist right now in America.
