The fear of trust in family.

Have you ever been in a situation where you need to trust someone, like your family? Let's turn the question around. Have your family trusted you?
I have been in this situation where my family does not trust me. For 6 years, I have been forcing myself to not feel, to not cry. But it always seems to fail.
For example, you have a cousin sister and a cousin brother. Everyone in the family loves your cousin sister, so she took the advantage of it. Every time where she did something wrong, she will put the blame on you. The that's where the problem came in. They don't trust you, even if you're not in the scene.
The longer it gets, the more corrupted it becomes.
What ever you do, don't reach that point.
It kills you, slowly and painful.
Please, don't.
