Sorry I'm late here... but I see another possibility. You touched on it briefly, Ales... but didn't quite get to absorbing the whole enchilada.
When we have feelings, what changes those?
How do we learn to let things go -- and what on earth DOES this mean, "let it go", existentially?
When we have the same crappy feeling, over & over, and over & over until it seems like dogma, reality, and the doomed fate of our lives... what is that trying to tell us?
There are different approaches to T. And within those disciplines, there's sort of a personal style to each T.
My T would let me tell my story -- until I got to one of those painful brick walls, and then simply let me FEEL the feelings and be there for me. Self-pity, in my case, was an avoidance technique for grieving my very real emotional losses. :shrug: In a way, it was functionally dysfunctional... my logic, if you can call it that, was because NO ONE ELSE cared, by indulging in self-pity I could at least acknowledge the existence of the fact that caring SHOULD exist in the world and that I was a candidate to be cared about.
We spent a couple years doing this. It felt like years, anyway. I had to get to know this from the inside, be able to see it from the outside like it was someone else's problem, puzzle over the alternatives... try some things on for size, see if they fit... and then one day - the bubble just popped. And the world was vibrant, fascinating, and charming... colors were brighter... birds were happy... and I was walking about 6 inches above the ground giddy-happy. (That wears off; life happens...)
The "work" that we did was NOT her guiding me to "do this", "feel that", "think this"... the work was simply her giving me her time and attention - and CARING - while I continued to suffer through really feeling my grief, my aloneness in my experiences of the past, until I'd REALLY let myself feel it - and realize, nope; I didn't "fall apart" into a blathering idiot or go crazy from it. It sounds so simple, doesn't it?
It was really hard work, for me. It must've been frustrating for her because my creative streak meant I was never at a loss for some evasive avoidance scheme. She had to repeat the above quite a few times, before I couldn't avoid the obvious anymore. The obvious is:
Life isn't always fair.
Some of us have more shit to walk through than others; but we all got our own shit.
Shit washes off.

One of the reasons, I think, that there are different kinds of therapy is because people are all so different. This (above) worked for me. Sounds like this T you described, and I would've hit it off. But it didn't work for YOU. That time, anyway. Maybe another time, and you'd be ready to face the worst of the feeling - feel it - and get to the point, where you'd know what to do on your own and be able to do it, without getting "stuck" on "repeat" of it. I took breaks; went back and then kept going. I must've learned SOMETHING, because even this horrible thing with my D and grandsons, as much as it triggers my old stuff - and feeling bad for them, too - is "do-able"... and every once in awhile, I can even find good, legitimate ways to help. Oh - and I still have my old quirks and my old avoidance techniques are still hard-wired into my brain.
But I can "see" it better now... and shift gears or change direction.
