Hey Alleris
I'm 43 now, I have been dealing with family neglect and abuse in about the last three years, I was dissociating for decades. I don't have medical records about any of it, but I was very depressed and had suicidal ideation (only in retrospect do I see it).
Dissociating is a way of protecting ourselves from having feelings that are too risky to express in an abusive family, it would probably have made things worse to protest, as a child. I have seen a counsellor too, and like you had a period of extreme anger and sadness. I have cut off my entire family, a remaining sister only last November. I feel at times very isolated until I remember I never really had them, so to speak. There is nothing to lose. Turning dissociation into righteous feelings of anger etc are what this is all about, as an adult, dissociation will get you nowhere, it was the tool of a child who had no options and no power.
It's ok that you're finally in a place where you can acknowledge your feelings about the past, it's not easy but given time you will get past it (this is what I say to myself anyway). I'm out of the line of fire now and the stress and panic responses are easing off. Why this morning I slept until 4 am, which is practically a lie-in. :)
What I did is turn it all into art, and I know that might sound twatty, but 3 years ago I just got myself a bunch of FIMO polymer clay and started making shit. I hadn't made anything in years, and you know what, it's really bloody good, what I'm making now. I have plans to sell it, got me a website and learned how to build it.
What are you interested in OP? What have you always wanted to do that you have been unable to do so far? I really believe recovery is about finding yourself, because your wants and needs have been buried for so long. Midlife is a crisis for everyone I think. To move past it with grace and into the second part of our lives takes skill, and especially so if you feel you haven't lived the first part at all, due to every fucker wanting a piece of you.
Create create create! Make new friends (I volunteer in a charity shop, working with old ladies, love it, my grandparents were cunts pardon my French). I haven't got many friends either, have had to ditch a few after realising how remarkably like my family they were. No matter, I am only 43 and the odds of making no new friends from now to 80 is very slim I would reckon.
Check out the stately homes thread about abusive families, if you haven't already. Come back at me with a list of dreams you have for yourself, no matter how outlandish. I'm going to retire to Spain, it's in my sights. You have my warmest wishes x
