"I am doing that to protect myself, not to make you cry or make you feel sad, but for you it seems to be a big thing.
I don't know what's your real problem. Whenever somebody says something negative about you, or tells you you did something wrong, you make a big thing about it and you are sad.
Maybe you should be more self-forgiving or self-irony, because nobody is perfect. Most people don't make it a big thing of it. You always want to do everything right and perfectly, to be perfect and everybody sees you as perfect, and when it's not like that, you are like oh my god the world is crashing."
That is how S sees me. I know I am not like this, but maybe he is right.
Though S still said something touching: your Mom should be taking care of you, not the other way round. You are the daughter and she is the mother.
