Why do I always think everything I do is wrong?

The answer to this may be unique to every individual, but acknowledging that you think that is the first step in knowing that it is not the reality of the situation. I first want to assure you that not everything you do is wrong. When addressing this question, it is important to think if there are specific situations in which you feel you are doing everything wrong. Is it in social situations? A work setting? This may help determine the anxiety surrounding why you feel you are doing something wrong in every situation. Perhaps consulting professional help would narrow down where the thought it coming from.
