Well me and a new member nonabug5 have wicked insomnia, right now she is going thru some tough flashbacks, and we speak on the phone almost every night describing our day and nightmarish times.
We could careless about the insomnia as far as what time we sleep, its the lack of sleep that gets to us. Well lately she is sleeping and I have been awake for four days with about eight or less hours worth of sleep. My legs are killing me, so I must be running from something when I do sleep (I trained myself not to remember dreams.) because my legs feel as though I was running an eternal marathon they hurt so bad.
We are similar in that we feel safe enough to sleep when it finally gets light outside, this morning it got light, and I made coffee, couldn't sleep again.
I find xanax to be very (extremely) helpful with reducing the anxiety, not the flashback, just easier to cope with.
Because nonabug5 had the same trauma as me, I understand everything she is going thru. It would help if you had someone from the site that understands your type of trauma, I am sure there are many, and ask them how they handle theirs.
Discussing with others helps, because we do things reactionary and may not have a clue why, speaking with others can help you understand your reactions and where they come from due to the trauma and like a puzzle being put together, a peice will fall into place making sense of what seemed senseless.
Hope this helps, ask anything, everyone here is helpful.

I don’t really sleep much atm. I find that I can’t get off to sleep because of anxiety and intrusive thoughts. If I do sleep, then I have horrible nightmares. Part of me doesn’t even want to sleep, because of the nightmares!
I guess one of my biggest problems in dealing with this is that I’m not very good at talking about things. Not very good at being open and honest about how I am. I’ve spent so long bottling things up and pretending everything is ok, that I’m not very good at opening up. It makes me feel really vulnerable. Like I am giving people ammunition to hurt me with.

Okay, meet some of my old friends. Control, I love him the most. Hyper vigilance, he keeps me safe. Karate, she let's others know with her eyes, she is not happy and can strike at any time. Innocense, she left me when I was three, I haven't met up with her again as yet.
Now meet the ones I want. Love, it's been since my brother's death since I saw that shadow. Friends, I've about given most of them up, they just don't get it. But I miss them dearly.
Comraderie, other like minded spirits I can prance around with.
No one on God's green earth can hurt me unless I "let" them, and even then, I may not admit it, though I am getting better.
No one can say or do anything to me I do not wish to partake in.
If I wish to hold in all of my thoughts, and keep my opinions and thoughts to myself, bottom line, I will explode, I am an extrovert by nature, a hermit by environmental factors, sometimes the two do mesh.
Ask yourself a question. What are the parts of life you want most, then ask, what part of the ptsd is preventing that from happening.
I bet there is a huge connection.
I separated from people long ago due to having my father and brother having and dying from Huntington's disease. They were the two people I only loved in this world, and the two people who God chose to take from me.
I figured at an early age, if you love them, they will die. But, that was a child's way of thinking.
I know believe I was the luckiest person in the world for having those two precious people in my life, and looking into others lives, seeing they have nothing like I had, I feel more sorrow for them, then they could ever feel for me.
If I want love, I need to free my reigns on control enough to give the other person what I have demanded all of my life, respect.
It was a heartache to do, you see control was my best friend, my most wicked enemy we were one in the same.
I will always feel in control, even when I am lying to myself, like now, I have given control up, just a tad,,,,,,,,,,,but no one was looking. lol
