Please help, can't understand dad ?

As a teenager you're going to crave structure and a routine, it's hard-wired in your brain from a very early age. I have been through a lot in my lifetime, overcome some very horrible abuse from my father. It's difficult to understand, how some families can get along and have somewhat healthy relationships, where you feel as though there isn't one at all. This is more normal than you think. Most teenagers start finding they have different ideals than their parents, even somehow are wiser or sensible. All I can suggest is trying to find a way to be out on your own as soon as possible, if he tried hitting you once it will certainly be in him to try again. Sometimes parents aren't fit to be parents and it's up to the child to find their own way. It sounds far from fair, but it usually produces a very strong individual who has an excellent sense of self. Hang in there and I wish you the very best of luck.
