@scout86 That was incredibly helpful too. I get the quote about being truly free when you have nothing left to lose and it sounds like my guy. Over half a dozen at least push/pull episodes over 2 years, it's either "you're the best thing I've ever had in my life, let's be together forever" or "I can't be in a relationship with anyone ever, it's impossible and it will end badly with us so I have to call it off now while we still can. Sorry, have a nice life." Always after we've reached some kind of milestone in closeness or communication with each other.
I'm honestly wondering, is this NOT the way a "normal person's" brain works? Because maybe it's not and it would be really useful to know that.
So I'll try to help with that, since you've been so much help to me. I can't say I'm a "normal" person or what a "normal" brain acts like. I also don't know that I'd describe someone with PTSD as not behaving "normally." At this state of my knowledge, PTSD seems like a response to trauma programmed into all of us to be helpful and adaptive, that has gone haywire and lasts too long and too strong for some people, maybe people who are esp. sensitive (vulnerable?) to their environments to begin with. I'm not in any way trying to minimize the constant, lifelong struggle that is PTSD, just hoping to share where my thinking is in case it opens up a new perspective for someone.
That being said, I as an individual am probably way far to one end of the spectrum in that I really do seem to process things logically and calmly as a default, even when I feel vulnerable. To me, feelings aren't facts, and if I learn a new fact, it often alters a feeling right away. If I feel threatened or insecure, I can always fumble around in my emotions and find some anchor of stability to steady me. I was very lucky that my sister and I were raised with tons of unconditional family love and support, so I've always drawn on that as an adult and had a generally positive feeling that, even when things got very bad, the world was basically going to treat me with kindness and everything would ultimately be ok. You might say my stress cup is pretty deep or hasn't ever truly overflowed.
So being vulnerable for me isn't a cataclysmic, terrifying thing. Sometimes I'm uncomfortable with it to some degree, but it's not a dealbreaker or something that I feel I need to run from at any cost. It doesn't preoccupy me or rend me apart at any deep level. So you might say people like me are lucky enough to have enough of a cushion built up at the right time to protect their basic sense of security when they need to draw on it. I realize more and more how rare that really is, and how just because someone else hasn't had that, it doesn't mean they aren't strong or can't develop the ability to cope and succeed--their responses are just as "normal" as mine based on the input that's gone into their lives. It's just that they didn't get the same head start on building up the emotional reserves required before they had to deal with life-changing stress/trauma. And of course there are things people with PTSD have experienced that no amount of "cushion" could help any of us deal with. It may be the luck of the draw: I've had enough cushion to deal with the particular things that have come my way, others didn't for the particular things that have come their way, and still others had so much stuff coming at them that a cushion to deal with it hasn't yet been invented. We all use the tools we've gathered up to whatever point we've reached in the game to fight whatever saber tooth attacks us, and sometimes there just aren't enough tools for anyone. Then we have to learn to live with the battle scars in a new way, which itself is a lifelong quest.
So I'll try to describe what I as a non-sufferer feel when I start feeling vulnerable, knowing it may likely sound completely nuts to people on the other side of the spectrum: "I'm feeling esp. vulnerable in this situation. Hmmm, if I stop to think about it, that feels kind of strange and uncertain and maybe a little scary. What's going to happen to me here? Will I lose, will someone not like me after all, will something unforeseen happen? Ok if I really keep thinking like that, more possibilities for it going wrong are now popping up. But wait: I realize thinking like that doesn't feel good, and I know on a very somatic, visceral level I'm meant to feel good, so therefore all that worrying can't be right, it doesn't make logical sense. I'll see my way out of this and I'm sure it will be alright in the end. It's definitely not worth worrying about when compared to all the plusses of loving someone, taking a risk for something that will help me, or getting enjoyment out of something etc. I'm just going to dismiss that feeling of being vulnerable if it's going to cause me to lose out on something.There: It's gone." Now, this might take a few seconds, it might take much longer, but the end is the same for me. So if you want to know what a supposedly "normal" person feels like dealing with vulnerability, that's one response. I imagine most people, PTSD or not, lie somewhere between me and my guy, for whom vulnerability seems to be a heartrending, insurmountable source of stress, one I'm trying to give every ounce of empathy to understanding.
I also think that, even though PTSD is a serious lifelong issue that sufferers definitely can't just snap out of, any of us can start where we are and build up our emotional reserves even in small ways that open up new possibilities to cope and be happy. I know that's not easy, but I can't help believing that we as humans are as hard-wired for that as we are to develop PTSD--science just hasn't given us the definitive techniques for doing it yet, or for fully dealing with PTSD. I respect the struggle so much, even knowing as little as I do, so please forgive me if I've said something that strikes someone as wrong. This is where I'm at in my understanding right now and maybe it will help someone see something new.
