Is self-doubt the cause of my anxiety?

Is self-doubt the cause of my anxiety?

Doubt may center on everyday concerns (Can I accomplish this task?), issues of daily living, or the very meaning of life itself. People in different stages or ages, ask themselves, what am I doing with my life? Either because they had some sort of plan, changes in their lives, opportunities, relationships, and decisions. Change is very common, it is inevitable. So, why the self-doubt?
