You're at what I think is the hardest part of therapy. The bad news it that it sucks to feel this way; the good news is that its a sign of real progress.
My T talks about it alot, how people go to therapy expecting things to get better, but they usually get worse first. There's a reason you've stayed away from these thoughts and feelings. At one time, you needed to to survive. And then it just feels too painful or even like it will overwhelm you to feel them Therapy provides a safe place and a person in which to quote my T "you feel safe enough to feel scared."
So the things that are emerging are painful and ugly and difficult or you wouldn't have put them away in the first place.
I just talked about this in another thread on Trauma, but traumatic memories are stored differently. Trauma, by definition, is something that you are incapable of processing when it happens. These memories are stored "raw" and actually in another part of your brain. Because they weren't processed, they have an immediancy that normal memories don't have. You know how you can remember feeling sad, but don't feel it with the same intensity? That's not true for traumatic memories. Part of what makes them so hard is that they feel like they are happening in the moment and they come back with all that intensity which made them overwhelming in the first place. And until they're processed they continue to stimulate and stress your system even though you're not consciously aware of it. Which takes up an enormous amount of energy which could be better used on other things, like being a parent, partner and person.
But therapy should provide you with the resources to process them. Once you have made sense out of them, placed a narrative on them then they lose that intensity and become a normal memory which you don't need to expend energy to contain.
The other benefit of going back and talking about your childhood is that most people who have suffered abuse were told lies, but lies that were laid down when you were very young, had no way to know they were lies and have become woven into who you are so that although you're not consciously aware of it, you're still living by them. Like my believing that no one else would ever believe I was attractive which I believed for 47 years not because it was the truth but because I was told it over and over by someone I needed desparately and had no reason to not believe.
And your also at that horrible point where you realize that you've come to far to go back, the old defenses won't work because now you're aware of them, but you don't really have a replacement for them, healthy ways to deal with the pain. I'm not going to lie, it can get really confusing, there will be (many) times you'll be tempted to quit, but I promise you it does get better. You will learn to live another way, to be present, to use that energy you spent containing those memories to do things you delight in. You will heal and break the power of the past which will give you choices you never knew you had. You can heal.
I have gone from feeling like I was shut in a lightless box where you couldn't lie down or sit down, to feeling like I can fly down grassy meadows. It was not an easy or quick process but it was worth every drop of pain. Think of it this way, you can be in pain and going nowhere, or you can be in pain using it to go forward. I know what I'd pick.
A quote from Winston Churchhill: If you're going through hell, keep going.
I'm so glad you posted and asked this. Its a really good question and the feelings that you're dealing with make so much sense and are so justified. The truth is you shouldn't have to do this. You weren't given what you needed and it sounds like were given things you REALLY didn't need but NONE of that was your fault. But its your life so you have to deal with it. But its ok to be angry about that, I know I am quite frequently.
And one last gentle question, why would it be bad to break down with your friends? You have suffered terribly and have much to mourn. Would you scorn a friend dealing with the kind of pain you are in if they were upset or having a difficult time? Your emotions and needs are legitimate and worthy of attention.
There is another side and you will get there. You've already survived it, now you just need to learn to flourish. And I stand by my signature line.
BTW, its taken me a long time, a lot of therapy, and two really good therapists to start making sense of this stuff so if anything I said didn't make sense or you want to know more, please ask.
