Hi Used2Be
My former partner has PTSD and he lives with us. His PTSD is from childhood and also from 2 tours in Vietnam. I also have PTSD (and we both have bipolar diagnoses - I accept mine, he says his is no longer current - but I think it is, whatever the shrinks say) so I can relate to your husband's symptoms.
My former partner also has a type of seizure and I think he was told at one stage it was an unusual type of epilepsy (I'm not sure exactly what), it makes him prone to suddenly going white (or yellow) and either passing out or nearly so and then throwing up. He's weak as a kitten afterwards. I've noticed he has these more often when he's stressed, and they are worse if he drinks much alcohol (more than one glass).
PTSD is often undiagnosed for a very long time, I've had mine since childhood but only got diagnosed in '09 after Black Saturday. It is possible, even quite probable, that your husband's PTSD goes back to his military career or before. No doubt his time in emergency services would have had a significant amount of trauma too. It is incredible what the human mind can live with and shield itself from for a very long time.
I really feel for you both. I've got 3 kids aged 6 to 17. It must be exhausting and terrifying for all of you.
Most of my life I've suffered from severe depression, and the way I learned to protect my kids from myself when I was in that space was emotional withdrawal. I was too fragile to deal with them very well (and usually couldn't cope with their friends coming over) and often told them I needed "time out" because I was stressed. I was frightened I would just lash out at them emotionally because I was so fragile and that would easily turn to burning rage. So it is possible the withdrawal is your husband's way of trying to protect all of you as well as himself.
One of the problems with my former partner's PTSD is that when he's triggered he can be quite emotionally abusive. It is one of the reasons we aren't partners anymore. I have had to learn to be very clear with him about boundaries for everyone's sake including his. So if he starts behaving in ways which are very inappropriate I tell him very calmly what he needs to do, and why I find his behaviour abusive. I know he doesn't want to hurt us, but at this stage he's unable to be fully conscious of his behaviour when he's triggered.
You don't mention whether your husband is receiving any (psych) therapy for the PTSD. I would recommend exploring this, it has made a huge difference to me in being able to recognise and manage my triggers (I'm happy to explain the other things I've found helpful in another post if you are interested). It might take quite a lot of work to find the right "fit" with a therapist, which is also very trying and tiring, but worth it in the long run.
Have you tried to tell your girls what's going on? They will probably be quite bewildered, frightened even - as you no doubt are (quite understandably).
One vital thing is to take enough time out to care for yourself, because you are carrying a huge load. They are all depending on you, and even without suffering from depression that can seem overwhelming. Whether you see it or not you are incredibly strong.
Kind regards,
Kristin
