I'm in the same boat. I had something pretty traumatic happen to me as a teenager and I'm still working through it. My mother is still working through an event that happened to her over 40 years ago. My husband is currently working through some PTSD as a result of his time overseas. I'm a little unsure where the line is drawn between PTSD and, for some, a lifelong process of dealing with things that have happened.
For those a**holes saying that you should "grow up" here are a few quotes for you:
"Posttraumatic Stress Disorder (PTSD) is an anxiety disorder that can occur after you have been through a traumatic event. A traumatic event is something horrible and scary that you see or that happens to you. During this type of event, you think that your life or others' lives are in danger. You may feel afraid or feel that you have no control over what is happening.
Anyone who has gone through a life-threatening event can develop PTSD. These events can include:
* Combat or military exposure
* Child sexual or physical abuse
* Terrorist attacks
* Sexual or physical assault
* Serious accidents, such as a car wreck.
* Natural disasters, such as a fire, tornado, hurricane, flood, or earthquake.
After the event, you may feel scared, confused, and angry. If these feelings don't go away or they get worse, you may have PTSD. These symptoms may disrupt your life, making it hard to continue with your daily activities."
"PTSD symptoms usually start soon after the traumatic event, but they may not happen until months or years later. They also may come and go over many years. If the symptoms last longer than 4 weeks, cause you great distress, or interfere with your work or home life, you probably have PTSD."

I think that it is so great, and important, that you're now in therapy to work through this. I didn't understand the extent of my pain until I made it to a therapist. My husband practically forced me to the therapist after he saw that what I'd gone through (years before I'd even met him) was impacting my daily life and our relationship. Mind you, this was a good ten years after the incident. Some people can make it through rapes, natural disasters, combat, car accidents, etc. just fine and are able to process and "deal with" what happened, but for others of us, esp. those who suffer from PTSD, it takes time, and sometimes therapy. (In my humble opinion, if you think that you have PTSD you should get yourself to a therapist ASAP!)
Okay, I'm getting off my soapbox. Sorry this is so long. Good luck, OP. Please don't feel childish about having a hard time getting past whatever it is that happened to you. If that makes you childish, then so am I, my mother, my husband, my husband's best friend, one of my close friends, etc.
