Therapy is the hardest work you will ever do, but the best/most important. Talking about trauma is usually very helpful...keeping it inside is painful...you could also write things down and hand them to your therapist. Talking with others who experienced what you did is also very helpful. I had a traumatic childhood (verbal and physical abuse, poverty, no father around and molestation. I kind of did my own healing with my sister and a few close friends....Saw a therapist for a short while; it was helpful, but I had already done a lot of work myself (reading, talking,etc).

If you don't (continue) to process the feelings (as you stated), they will continue to "bubble up"--it is the mind's way of urging you to confront them.
