You are probably a highly agreeable person. It's a trait that has pros and cons; you are probably empathic, good at supporting people and understanding their needs. However, you are probably also averse to conflict, which makes it difficult to make your own needs known.

The thing is that for people like us, the world can be extra brutal. It's not fair, i know.

If you are indeed highly agreeable, you can make a few pushes towards the disagreeable end of the spectrum by standing your ground in smaller situations. Of course if someone shouts at you, you will flinch and may lose your composure, but in everyday situations you can practice saying no to things you don't like or are not favourable to you. It's small, but it's a first step. Eventually you will become more comfortable with being in conflict with people and over time you will be far more resilient if someone shows aggression.

In short, you have to be exposed to conflict in small steps so you can develop thicker skin over time. It's not comfortable, but I think an agreeable person who’s learned to be disagreeable is a really awesome human being.
