Thorough research is gonna be your best friend here as far as symptomatic stuff itself, especially resources coming from other systems. However, I'm gonna address specially the latter portion of this post by saying this first: there is no objective margin set for how traumatizing something was to you.
What isn't traumatizing for one person can be absolutely devastating to another, and I do mean that in the most genuine way possible. (This difference can be especially stark looking at neurodivergency, but it's in no way exclusive. Additionally, growing up neurodivergent in a world designed solely for neurotypical people is traumatic on its own- not something can put into words, but I know I've heard lots of others talk about it.)
For example- moving, for some kids, is totally fine and normal, even a positive experience in some cases. It could be a negative experience, too- upsetting, scary, but not necessarily traumatic. For others, though, it can be genuinely debilitating. As a kid, having your entire world turned on its head like that, losing all of your friends, any out-of-home comforts, your sense of familiarity in your surroundings and the security provided by that, and very possibly your own belongings if anything had to be left behind. Your entire sense of stability and safety and knowing is ripped out from under you, and for a kid still learning how to function and process, especially in already unhealthy or abusive situations, or if they have strong sensory issues and/or an aversion to change, that shit has an impact! Is moving as a kid traumatic to everyone, absolutely not. For many it's a normal part of life, so the idea of it being a traumatizing experience seems ridiculous- but for some, it did affect them that way, and minimizing that by generalizing experiences will only worsen the situation.
All that to say that what's 'bad enough' and heavily traumatic is different with everyone. It's circumstantial, it's neurological, and it's deeply, deeply personal. That said, I'd say emotional, verbal, and sexual abuse are absolutely pretty traumatic regardless, it's how it impacted you specifically that deems it 'heavy'. (And, believe it or not, most people would already consider that pretty heavy on an objective level!!)
Thing is, a lot of misinformed people tend to play up how severe someone's abuse surely must be to develop DID and similar disorders- they think cults, they think trafficking, they think being locked in a closet for weeks on end with no food or nearly killed- but that isn't a qualitative measure. What's more important is how consistent it was. According to the current theory of structural dissociation, everyone is born with separate parts of the mind that integrate in semi-early childhood to form one 'complete' person. Disorders like DID or OSDD-1 are the result of the childhood environment being persistently traumatic and unsafe in a way that inhibits those parts of the psyche's ability to mesh together, instead encouraging various amnesia barriers (emotional, full, partial, etc.) to keep the kid alive and as safe as possible. The priority isn't on growth, it's on survival, and children are vulnerable, so it's especially important to bear in mind how the perception of trauma changes- similar like I talked about above, what can be just a bad experience for an adult can be traumatic for a kid, and things that are traumatic even to adults — like abuse of any form — can feel even life-threatening, regardless of if it actually was or not.
If we're being honest, we empathize a lot with your experience, because we felt — and sometimes still feel! — how you do. Emotional and verbal abuse are downplayed to a disgusting degree, and it can manifest as a lot of internalized 'this doesn't really count as abuse' when considering your own experiences. We experienced a lot of emotional abuse and neglect, and we're still coming to terms with even the possibility that we were SAed when we were young, only having considered it at all relatively recently, despite both knowing we were groomed and that our sibling was SAed (something we were told, we didn't know beforehand), possibly even multiple of our siblings. Amnesia is one hell of a blinder, too- things may not seem 'that bad' because you can't remember the full extent of it, or because you can't emotionally process the damage that it did. We have general bits and pieces, but we know they aren't exhaustive, because it wouldn't make logical sense for them to be sole incidents- those likely less severe pieces are more like little cutouts of the full picture that couldn't or can't be dealt with, meant to surface when asking what happened so that there's something there that's more palatable than the entire scope of things.
A lot of words, my apologies, but I say all that just to emphasize to you: as you research and feel things out, try not to put as much worry about what conventionally might 'count as traumatic enough' to warrant it, and focus more on your experiences. Not necessarily the traumas themselves — usually very unsafe to do on your own — but how they've impacted you, and what influence those experiences might've had on your psyche.
Much (platonic) love from the requiem; we know how you're feeling more than we can describe. Definitely do some researching and introspection— and know that what you've experienced, and how it's affected you, is real, important, and valid, no matter what you find. <3
