Becky is insecure because many things in her life have gone wrong and she is tired of it all. It is normal in our life that insecurity take over and the fear of failure makes us want to stop trying. First of all, before trying again, before looking for solutions, Becky must breathe. Deep breath. She must remember that failures are more of an attempt to get right. If she failed, it was precisely because she was trying to do something right. She can be much more than she is thinking and she can not let mistakes discourage her to be more.
Insecurity and Afraid to fail often comes together. In my opinion, her being afraid to fail is taken from her insecurity or lack of self-confidence. The person who have issues like this often falls for depression and uneasiness. There are many circumstances that affect her self-confidence. It could be something at home or pressure from her peers. Becky has to learn that sometimes, it is ok to fail as long as she learns from those mistakes and conquers her fears. Becky has to learn to love herself and accept her shortcomings.
