What is wrong with me if I am constantly second guessing myself?  I started a new job a couple weeks ago, First time in this field (an office). I understand most of what Im doing, but I feel like Im messing up (even when Im not).  Its not only at work. I find myself second guessing myself at other times too. Im 55 years old
Degree understand your concerns went through your details. I suggest you not to worry much. Even though the symptoms you gave are not enough to diagnose your problem, I sincerely think that you need rest for a couple of weeks. You seem to be stressed. I also think that your family life is also affected, if you have a family. Otherwise, not having a family could be the basic problem. Consult a psychologist. If you require more of my help in this aspect, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe the needed psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck.
