There is a laud voice inside me when i come to s/o and they can hear

friends am shyful man so i cant share my feelings openly to anyone. unfortunately some mistakes i have done. now when i come to s/o there is always a loud stronge voice of my faults related or else like bad word toward myself or s/o others comes inside me. i feel frightened and sank on that voice. sometime many bad images comes in my head and that also cause me same. both voice and image can be easily listened viewed and understood by people around me. even the small child above 8yrs can hear and visualize my thought and imagination. my sisters child of 8 yrs also hear my thought without staring at me. pleaz give me solution?
