thanks for question
First of all ask yourself whether the voices you are hearing in your head is your own voice or its coming from outside?
then whether others are able to hear this voice? or they are not understanding your problem?
if these voices are vague sounds or well formed voice?
are you able to control these voices by closing your ears?
are you able to sleep properly?
are one of important symptom in some psychotic disorders which resembles symptomatology you are describing.. and they are usually distressing to affecting individual, and usually ask to do derogatory things.
Second possibility in such situation is in obsessive compulsive
spectrum, person is compelled to do a particular thing otherwise some bad will happen. Its more or less similar to magical thinking.
Dear friend in both of the situation you should consult a good psychiatrist
. And don't worry treatment is possible in both cases. Try to interact with family members and discuss with them regarding the problem.
thanks and hope you are satisfied.
