I don't there are hidden fears inside me,like whenever after conversing with people,I leave that place,I fear of people talking ill of me behind my back or criticising my behaviour,attitude or thinking.I know criticism is sometimes good but many times I take all comments to heart.

How to handle this?

In the same way,while saying 'no' I fear that the person will harass me after that or use physical force against me if he/she can't handle it..

for example, i do not care what others talk about me.

We should just try to pray for others. Good things is always stronger than bad.

If You pray for those people who speak bad of You then You won't get any reaction and become angry.

Krishna is in everyone's heart. when You please Him then You will become dear to Krishna and it mean You will become to everyone also automatically.

Krishna is the root. When we give water to the root whole tree will be satisfied.

There is not any material solution for these things.

And plus we should think ourselves as an insignificant servant. If someone gossips about us badly then if we feel ourselves very tiny then it won't painful.

And also if some one tries to criticize You then just know that You are soul - eternally beautiful, intelligent. But when we think that we are this body all the problems will begin.

But always remember that some day You will be back to Your original position as a servant of Krishna in a spiritual body, in the spiritual world. In this way You will be able to take easy problems of this world.

Just bring Your mind into Holy Names and always pray to Krishna to help You.
