I think most of us hold it together for a long time before we crack. Supposedly delayed onset PTSD is more common than getting PTSD right after the incident. I didn't crack for 25 years. I have heard of others who have held it together for a lot longer. Yeah, it does suck. But, therapy isn't about just talking about it. Just talking isn't going to heal you. Its all about processing what happened to you, dealing with the feelings, and finally being able to put it in the past where it belongs.
