Feeling terrible

I just am feeling so terrible.  My dad has been in a good mood.  That is the only good thing.  When he is upset and or frustrated- he'll raise his voice and sometimes even yell at me. He gets frustrated and upset quite easily too.  My dad also can be controlling and bossy.  

I don't tell my parents about my struggles since they'd overreact which I can't handle.  It'd be too much.   Even if I told mom- she'd tell dad.  That is not fair even if I told her not too- she'd still go and tell him.   So I feel the need to tip toe around both of my parents
