I completely understand the "I don't have PTSD, I mean, it wasn't that bad..." I was diagnosed and waited seven years to get help because I didn't understand that what I went through wasn't normal. I thought that all the times that you were told growing up about things that weren't acceptable and should be reported, I thought it was just a thing they said, and that it happened to everyone. That everyone had the same experiences I did.
I ended up finally caving when I had about a month of isolation and suicidal thoughts. I actually attempted once, and scared the crap out of my friends and the loved ones who knew about it. I was breaking down into pieces any day I had to talk to anyone, and I just couldn't operate. I had maybe an hour or two a day where I could talk without sobbing, and the rest of it I had to either sleep or hide in a room alone with a book to keep me from thinking about my life. It was awful.
I have, only the last handful of years realized just how anomalous my life was. How many things I thought were normal were actually unique among those I knew. About what happened and how I developed and how very frighteningly unusual it was.
I don't know if I'll ever truly "get over it" and be "normal" and I'm both pissed off and saddened by that. I will however, learn to live within my life now. To accept, to be able to function again and to be able to live my life better than I ever thought possible. I will minimize the damage as each year passes by and while it will never be gone, I can learn how to cope and manage and compensate.
So, yes, I understand not wanting to accept a diagnosis.
I also, sadly, also get the "PTSD faker" mentality. The sense (incorrect) that some people are "faking"-I expect it's simply part of the issues I have. I do my best to refuse to think that way and I call it out for the bullsh*t thought that it is. No, I don't understand how someone can be traumatized by seeing something on TV, no I don't get how someone can be traumatized by hearing about something. That doesn't mean it isn't real, or that it's "fake" -it means that I lack the capacity to understand because of my own blinders. It's not a valid thought, it's part of the part of me that pretty much hates everything and one (especially myself). It's not a part of who I am, but a part of what holds me back and hurts me.
So yes, I get it. I feel it. But that doesn't mean I have to believe it, and as long as I recognize it's part of that darker part of me, I can refuse it.
It's okay to be angry, but know where it's coming from and why. You're not a bad person for thinking it, you're just still grappling with that darker, angrier part.
