I can relate. Frankly, I think, at least half of the population suffer from C-PTSD and it's not even considered a real thing by the mental health profession.
I too mean absolutely no disrespect to survivors of combat trauma or trauma resulted from sexual abuse. I have no intend to downplay their suffering. I just think that trauma, as a mental condition, is a much broader phenomena than how it is currently defined and that many people are, unfortunately, left out of that category.
I do believe that C-PTSD manifests itself somewhat differently from classic PTSD (that's why it's called "complex"), but it's a legitimate trauma that has to be recognized as such.
So, yes, you are not alone. There are many people who have a traumatic history different from sexual abuse or combat, but their trauma is no less legitimate.
