Let me preface this by saying this that I am an adult..... All feelings are okay, so if you are feeling upset that your parents don't support you, that is perfectly fine to feel that way.... feelings are information about ourselves and are not wrong- what is wrong, is when people use those feelings as justification to kill.... but anyway, your mother calling you that is absolutely wrong. A parent should never call their child names. I wonder if you can throw in an extra thank you over dinners so that you feel better, maybe ask them if there is something you can help them out with around the house..... I am so sorry you are doubting yourself- parents do not realize how damaging they are to their children when they say awful things like that.
