For whatever the reason might be, at some point in time, someone you know well might have gone through a phase of self-hatred or self-loathing. Self-loathing is a strong negative emotion that stems out of low self-esteem and low self-confidence.
Failure, rejection, loss, or abandonment can be some of the causes that can lead to self-loathing or self-hatred in a person. People who suffer from self-hatred hold themselves responsible for any failure or rejection they face in life, not understanding that it is not them, but the circumstances that are responsible for the wrong happenings in their lives.
Self-hatred can lead to anxiety, depression, isolation and it can be difficult to pull yourself out of it. But it is possible to learn the techniques and strategies which you can use to change your thoughts and start to love yourself again.
