I don't know what i feel, i think i am an idiot

I don't know how to start. Maybe i should start from a little introduction. i am 23 years old, confused most of the time, work as a programmer in a mnc but want to try hands in government jobs "again".
Again because, i appeared in cds exams, cleared, conference out twice. then i joined this mnc. now i am not satisfied with the corporate culture and want to switch again... i am not sure whether i should or shouldn't. i feel like I'm an idiot. i want to tell this to my parents but before joining mnc i convinced my parents for this job, now if again i will tell them about my thoughts, they are surely gonna get angry badly.

i don't know, is it normal??
