For a long time, I refused to talk to anyone about anything that had happened. Most people didn't (and still don't) even know anything happened and I didn't think they would have believed me. It hurt too much. I internalized everything, didn't allow myself to feel anything about it, no matter how badly I needed it. As you can imagine, that took an overwhelming toll on my physical and emotional wellbeing. It got to the point where my mental health was severely deteriorating (yes, even worse than before).

Talking to the one person I trusted... Finally getting out things I'd been keeping inside for years... It likely saved my life. I won't lie, it was one of the most difficult things I've ever done. The memories and emotions were so intense, so raw and painful... but it was one of the best and most powerful things I could have done for myself.

In short, yes, in my particular case it helped a great deal. It still does on my bad days. Of course, everyone is different, and being ready to talk about it is a big key.
