Yes, it did help me in dealing with the past. It didn't help me much with learning how to tackle my other life struggles I was dealing with at the time, but it did help me process the abusive past to the point that I learned how to protect myself from those who abused me and came to terms with those events and with those people to some extend. I was processing my pain and anger for a long time until I became emotionally detached from it enough to be able to see the big picture and to see those who abused me as people and not as monsters. I was still keeping a healthy distance from them but wasn't judging them as much anymore. It helped big time. It made me more peaceful and more accepting of myself.

Nothing is perfect though. My work isn't finished, and I don't believe it ever gets finished. I still get triggered by certain things and I think I will for the rest of my life. But I deal with those triggers much better now.

If you want to heal completely, meaning that there won't be any trace of your past and your trauma, that's not going to happen and this is something you'll need to accept if you want to get better, otherwise you'll have a never-ending disappointment. But if you want to heal to some extend, to cope with your trauma better and to have a more fulfilling life as a result, then yes, it is absolutely possible.
