I also have severe difficulty parsing noise streams. Cross talk blends together. Misophonia can be bad especially with repetitive noises, especially when they're unnecessary.
I don't mean to suggest that anything traumatic or abusive was deserved.
I also don't mean to suggest when I use the word karma that I'm attached to the Hindu caste system or anything like that. Karma is a useful term for shifts in polarity between service to others or service to self. Moving along that axis in any direction is a karmic thing.
I haven't gone through what you have (as far as I know) but let's just say that I have the stars (astrological birth chart) to back me up when I say I've been through a childhood gauntlet of sorts as well.
As an adult, I've been homeless before. Eaten expired free food. Worked multiple jobs though. It was just that I graduated right into the financial crisis that gave rise to Bitcoin and nobody was hiring. Didn't matter if I was smart. They were all in damage control.
That said, here is what my research has yielded.
Kids mad at their parents may say something like "I didn't choose to be born to you." Basically, that's not exactly true. Both Dr. Ian Stevenson MD's research and Dolores Cannon's research suggest that we have a say in where we incarnate. We choose the conditions into which we will be born because we think those conditions offer us catalyst we need to polarize in the way we wish to continue to polarize.
So, from that perspective, I chose to have a very difficult childhood by choosing to be born then, there, to those people.
Now here's the flip side.
I wouldn't trade any of the suffering I've endured between now and my birth because without it...the butterfly effect...would I even be the me that I am today without it? Conceivably, no, which means I wouldn't feel like I understand things I never thought I would.
From what I've seen, we almost preprogram our subconscious mind to offer us experiences that are helpful for the ways that we want to develop so to a certain extent, the challenges we fight are self imposed pre-incarnation.
Here is one way I think about karma. If someone commits suicide, they likely still had unfinished goals for this life that were established pre-incarnation. If that's the case, as soon as they get back to the other side, they're gonna be like "Damn! Why did I do that? Now I have to go start all over as a baby, forget EVERYthing, and work through the same lessons I didn't complete because I hit the exit button." Our own desire to develop is its own form of karma between lives and it 100% includes our free will.
I wouldn't be surprised if some of the things you endured as a child were the origin of any of your clairs. My awakening was one of the most stressful moments of my life but all I could do was surrender.
Births are often traumatic. It would make sense for "death" (da'ath in Kabbalah, Gnosis, Vishuddha, etc.) and rebirth (born again, Phoenix rising from its own ashes, etc.) to, as above so below, be traumatic.
