Don Miguel Ruiz says:
" Nothing other people do is because of you. It is because of themselves. All people live in their own dream, in their mind; they are in a completely different world from the one we live in." Still, when we hear disgusting comments directed toward ourselves it affects us. I'm sorry about your situation and how this makes you feel.
Sometimes, we simply can't control what others say to us or about us - but we can control how we react to hurtful comments. At times the only way to respond to hurtful comments is to directly confront the offending person and request that they stop it. In some cases, it's best to just walk away with no response whatsoever.
To not let others hurt you, it may be necessary to stand up for yourself and make a retort when you disagree with what they say. This allows for expression, which pretty much helps to clear up the negativity inside you. Trust me — it will make you feel a lot better when you express yourself and you will at least know that you did your best and everything you could against things you disagree with.
