If you have/are experiencing being bullied; the first and more important thing to recognize is that it is not your fault.
They are taking out their issues out on you. Maybe they too were bullied and/or abused in some way. Some people cope with stress in a negative way and hurt others as a result. It could be a coping method for whatever it is they are going through/have been through. Maybe they are angry and insecure. They could also possibly be jealous.
Most of the time bullying is done to have power and control over someone else. They will target something specific about you to create or worsen your existing insecurities.
They are most likely people of low self-esteem and use bullying as a way of deflecting, and many times and more specifically; projecting their flaws onto someone else. There is a good chance that whatever they are pointing out that is wrong with you is something they are insecure about with themselves. They are not happy people.
Bullying is never okay but understanding why it is being done can help tremendously in the healing process. ♡
