What can be done to help you get through this?

I cannot stress this enough but finding a skilled therapist or counselor is one of the best things you can do.  You don't need to go through this alone.  I found a wonderful therapist in my early twenties to help me.  It was a difficult and painful process but I can honestly say that therapy does help with this. 

There are also support groups for PTSD as well as sexual abuse where you can talk with others who have been through similar experiences. You are far from alone in this. There are many others who share your pain and have survived.

Here are some further resources :

The National Institute of Mental Health has an index of articles about Post-Traumatic Stress Disorder that you may find here. 

If you need to find a therapist you can use the National Mental Health Services Locator  

The Anxiety Disorders Association of America  may also be a way to find a therapist skilled in handling both sexual abuse and PTSD 

You may also find information and assistance from the  Sidran Institute:  Traumatic Stress Education and Advocacy 

And lastly here is an open directory of support groups for sexual abuse survivors which you may find here.
