I haven't read everything that was written by everyone else, so forgive me if I repeat recommendations.
Acknowledging it first and foremost is most likely the biggest step. The extent to which the abuse occurred can only be measured by the individual. Although you may not perceive it as being serious, the impact of what happened has apparently affected you greatly. Never compare your story to others, it is your story. You deserve to be heard.
1. Start journaling. Put pen to paper and start logging your thoughts, your feelings, and your emotions. Don't be afraid to write your story down in your journal, and process the feelings associated with it.
2. Talk to someone, get a therapist if you can.
3. Consider going to one of the Weekends of Recovery. That may be very helpful to you.
4. Lastly, stay on here, read what others have written, and connect with others that share something with you.
Im sure there are many things you can do. But these are great places to start. Make your choices cautiously, and thoughtfully. Don't feel as if you are alone, there are many of us here that are right there with you.
