Trying to be brave...

This is the first time I'm "talking" about something that happened to me almost 20 years ago, so I'm just looking for some advice and support.

When I was about 7 years old my babysitter's teenage son used to sexually abuse me. I didnt even remember it happening until high school, when I suddenly got flashbacks. More and more of the memories have come back to me in pieces over the years (which I can only assume is because I subconsciously blocked them?). I'm honestly a little scared that more happened that I'm not remembering.

Anyway. Sometimes it's harder than others for me to deal with. I tend to suppress the emotions until it erupts.

I'm terrified of telling this story to someone in person (a licensed professional). My very supportive bf knows I was abused, but that is the extent of it.

Any tips on how I can seek better treatment and the courage to do so?
