What did I do wrong?

People are so critical of when I get upset.  Things for me aren't so good, anymore.  In a way, they are, I have to see, that things should always be okay at some level.  If I do something normal where I'm mad but not actually intentionally, people get at me in unproportionate manners.  They all want me to learn certain things on how to live my life but never do it in words but rather take up my life in order to do it.  I thought if someone did something to you, you could be upset or do something about it or change your ways, hopefully though that you find a good way to change things.
