Gracebuttercup, rape is rape. You experienced a severe trauma and it will absolutely have impacted you. There may be plenty of times you are able to keep the effects of that trauma at bay, but the effects will be there (as you are discovering with the recent trigger - most people seem to find ways to manage the effects of trauma until particular triggering events come up in life) and there are things out there that can help you with that. EMDR is a relatively quick and successful treatment for single event trauma. But it isn't the only treatment out there.

You have choices and options, whatever work best for you. You can let it lie and manage it as best you can (that works just fine for some people) or you can seek treatment that will help with that. But you hush now on comparing your trauma to others that may "have had it worse"! Trauma is trauma, rape is rape. It damages, it scars and it hurts. It is perfectly okay and just and right to begin to heal yourself from that harm that was caused to you.
