A time when I felt completely lost

There was a point in my life where I wasn't doing good at baseball, and basically baseball is like my favorite hobby, I felt pressure because in my head i had the mentally of thinking that if I dont do good once, I'll never become the professional player i want to be in the future, I felt lost because baseball is the only thing i have. In the present, I know athletes do well in their sports because they practice more than normal.
