The fact is that you have grown up with beliefs and it was the only choice for you. This is because you did not know whether those beliefs were true or not. You just trusted those words from those people who are closer to you. It’s natural because those people are the ones who were helping you.
They are not wrong either as they also did the same as you did, that is, trusting in those words. Do you know that since childhood, you go on developing those beliefs? This means that those beliefs that you came to know via your parents, teachers and other people did not remain just like that. You went on developing them gradually.
What happened next? Problems started arising and you started developing stress and illnesses. Life became a problem for you.
