atelophobia

Atelophobia (from the Greek: ατελής, atelo, "imperfect, incomplete" and φόβος, phóbos, "fear") is the fear of not being good enough or imperfection. It can be very severe in some cases causing depression.

"Some individuals who have Obsessive-Compulsive Disorder fear that they are not doing everything “right”, or that they will make some error in their daily routines unless they check and recheck. Many phobias stem from a fear of being imperfect. Many individuals are unduly concerned with what others think of them and hence develop a phobia of imperfection. Examples of fears of imperfection are talking on the phone, going for a job interview, writing in front of others, eating in front of others, or speaking in public
