I have an INFJ friend and she holds in a lot of things that bother her. I know people do things that bother her she won't speak up about it. Instead she internalizes it and just deals with it. Basically anything that hurts her feelings she will she keep it inside and won't share it.
Do you experience similar things? Do these things build up inside of you and eventually drive you crazy? Does it ever help to talk about it?
