Is this Complex PTSD?

I read the very interesting article posted by DocJohn. The woman in the example experienced years of extreme trauma. I wonder if I have complex ptsd and what treatment works. And how long it takes.

I was neglected and emotionally abused as a child (repeatedly mocked and shamed and blamed for my mother's problems but rarely physically abused, generally felt unsafe). Then I was in an emotionally damaging marriage for 20 years where I lied to, blamed, ignored, cheated on. But I felt guilty that I was a bad wife and that was why I was treated so poorly. And I kept giving this guy the benefit of the doubt one past when any sensible person would have. I was divorced at age 50 and felt like I was finally going to have a life. Then, a few years ago, shortly after the divorce, I went through several traumas related to physical pain from a chronic health condition and mistreatment by healthcare workers. Some was unintentional by clueless people who did things to worsen my health condition/pain and one just a nasty nurse in a hospital, a big guy who was very intimidating and threatening and made my pain worse and made me feel unsafe. Nothing like this compares to that poor woman's story, and yet, it is the same in that it was repeated over many years. So is this also complex ptsd?

If so, any advice about how to go about treating it? I was not aware I had ptsd until it kept waking me over and over starting about 6 months ago. As my sleep got worse, my symptoms got worse, including flashbacks to the hospital and panic attacks.

My therapist who was treating my generalized anxiety and depression (from loss of job and chronic pain) diagnosed me with ptsd. She would like to try something called brain spotting, which I guess is like EMDR. I take xanax at night to sleep or I do not sleep at all. Well, I sleep for a few seconds or minutes and then wake up with a feeling of being startled by something (not a physical jerk, an emotional startle). But that sleep was not refreshing and I was a wreck. Tried many things and only the xanax worked. It dampens down the startle feeling that wakes me so I can fall asleep and stay asleep longer. But I cannot stay on xanax forever, in fact I think I am already having adverse reactions to it. But I need to sleep and I don't know where to start.

Has anyone experienced anything like this sort of sleep problem? Has anyone successfully treated complex ptsd?

Thank you to all who respond. I will be reading but sometimes my fingers hurt when I type, so then I don't post.
