<human>: Give me a shortened version of the text

This isn't about depression or anxiety. (Well sort of is but not looking for counselling or anything just advice)

So I used to get bullied alot and abused a bit by my family when I was a little younger. Recently I can't bring myself to say NO to someone or say that they are wrong in the fear of getting my ass kicked, which further leads to me being socially awkward.

A few weeks ago my dad (who is sort of a hardass) beat the shit out of me because I told him I didn't want to get a haircut. I'm 18 right now by the way. School has recently started and it just...idk affects me kind of in a way.
<bot>: Too scared to say no or tell someone that they are wrong because I always get teared a new one. What to do?
