Hi, Consult a psychologist for psychological assessment and counseling sessions.

Hi , Consulting a Psychologist will help you in managing fear by Understanding what is causing this fear in you and allow you to address and work through it by examining the thought processes causing the fear and replacing them with positive thinking patterns. 

Hi How long has it been since you have been scared of small things? It is necessary to know what is making you feel scared. You were once a bold and daring person and you want to become that person again. It is important to remember that you can feel better and calm. To feel better consult a psychologist and explain about your fear. Counselling sessions will help you. Do take care.

Why you have changed is something what we need to find and understand how to overthrow it.. Consult a psychologist either online or offline for a consultation..

Hi.. Is it right to say that you experienced panic in such situations? If yes, than it can easily be addressed with Cognitive Behaviour Therapy (CBT). You being bold or daring has nothing to do with this fear/panic response. Our brain, especially the animal brain, is susceptible to such cues that emulate any kind of physical threat. It used to be important for our survival in ancient times against our predators. But now in modern times those physical threats are being replaced with financial, emotional, social, or psychological threats. When we feel our survival is under attack our mind generates that typical fight, flight, or freeze/panic response that you have experienced. I am explaining the aetiology of this fear/panic response to you to help you understand how natural it is for you to feel this way. There is certainly something you have repressed but your mind is very much aware of it and it feels threatened. It can be anything related to your personal, professional, family, relationships or even spiritual or sexual life. But it is imbibing a fear response in your subconscious mind and it needs to be identified and addressed in a therapeutic setting.
