I'm depressed, but have no idea what to do about it (im 14)?

I had an unimagineable childhood. and now am just really really depressed. yesterday my dad said very angrily to me "why do you always look like someone sh!t in your cereal (metaphore of course) does your life suck that much?" I (in monotone with no facial expression) replied "yes it does" and he got even more upset. but anyway. when he asked that i just wanted to tell him how much my life does suck. but i quietly went to my room and cried myself to sleep. I wanna tell someone sooo bad. just tell them all my problems and cry while they hug me. but everytime i try to, I can't. I jsut stop. and quietly sit there. what should I do? Do you think i need some kinda therepy or something?
