I don’t say no, I say yes and put my discomfort for anything aside, other people’s wants are more important than my feeling

I don’t know why no one is mentioning this, but your feelings are valid and important. Assuming you extend this to people you’ve just met, eventually someone will either take advantage of this or think you like them because you don’t say no, even when uncomfortable.

Don’t do that to yourself. Whatever you did (as a kid), you don’t deserve that.
