Dear Anjali, the gap that has occurred in your career is not exceptional. It is common among all women. A career gap due to pregnancy is not equivalent to an education gap caused by failing an examination. Therefore, remove this sense of guilt.
Possibly, the cause of your nervousness could be a lack of knowledge. Confidence stems from knowledge. Therefore, build your knowledge. Review the discussions that occur on this forum. This forum serves as a window to the outside world. People share a whole host of problems they face in their workplaces. By reading those threads where seniors contribute their replies, you will gain valuable insights. Additionally, stay connected with HR books; they will be beneficial to you.
