What are My Triggers ??

Well, I really didn't know what triggers meant for Me but I realized very Quickly today. My triggers are My Boyfriend, Aggressive Driver' s, Light Blue Cars or Trucks & Sometimes People whom act like they are up to No Good. I guess I got to start peeling off the Layers of My PTSD Disorder but where do I start working on My Healing.
Should I start from My Molestation as a Child or should I start from where I got robbied at Gunpoint. Hard Questions for Me. Can anybody Help Me ??? So Confused & I feel so alone but I know I am not alone. Life Sux alot right Now because I can not put some peroxide on it, healing onitment & a Band - Aid. Well, I guess I have started the task to My Healing Process. But need INPUT.
