hey there :)
Yes, I've been abused too (by my dad too!) and I'm pretty sure I know what you're going through right now. The last thing you think you need is human interaction, because you think no one will understand, but trust me, human interaction is exactly what you need.
And I don't mean someone you can rant to, although yes that is EXTREMELY therapeutic (if you need someone please feel free to PM me), but as for people around you who might not understand what you're experiencing, just hang out with them as per normal. TRUST ME it really takes your mind off of things.
With the right group of people (your friends'll be GREAT), you will once again feel like life is worth living and trudging through sh*t for. Get close to them, be in touch, and be amazed at how great just being around people who care feels.
As for an answer directly related to trauma, as I said feel free to PM me, but as of now, as someone who's had a pretty bad past, I can tell you that you'll never forget it or 'get over it'. It's just not possible. What DOES happen, though, is you learn to live with it. Only when you accept this can you be at peace with it; relative peace, anyway.
Listen, sweetheart, everyone's got scars and battle wounds, some worse than others, but everyone's got them. And everyone feels the same fear, pain, misery and loneliness on those nights the demons come out to play. You're NEVER alone. Honestly, I'd love to make friends with you, and don't worry about being whiny because I'm pretty sure I'm just as (if not more) whiny as you could possibly be! HAHA
In the meantime, please take this advice and go out and participate in life. I'm not saying it's going to be easy (it definitely won't), and you're going to dread it before it happens, and just before it starts, but if you make the conscious effort to put that heavy feeling aside and throw yourself into whatever activity it is you're doing, trust me honey you are going to feel ALIVE. Like you own the world again.
ALL THE BEST!!
