Worst Phase. Handle it. i am helpless!

Nowadays i am feeling insecurities about my personality, as i am not very much bold, confident nor i am not able to express my inner feeling what i feel about them or the situation. I am like a introvert and i bearing all this burden of feeling and pain which has caused my internally weak and now i feel like i couldn't be able to be bold throughout my life, my parents were strict and sensitive about me from my childhood, i did not have any good memories about my childhood, because i have not enjoyed my childhood. From childhood i was under the shelters of fear, which i was not aware at that time. Now i feel like all these fear, low boldness, low confident are because of my parents. And i am not able to correct it by myself, i tried my best but i failed terribly and now feel its the end. I do respect and love my parents but somehow i felt to scream it in front of them, but i do not want to hurt them. I am holding many feelings and emotions which i am not able to handle it. I am helpless
