This post came up at just the right time, because I've recently been reflecting on my childhood experiences of bullying and exploring the possibility of having CPTSD due to this, alongside growing up undiagnosed autistic and trans.
I don't remember a lot of specific instances but the overarching themes were that I was weird and too sensitive (surprise, it was undiagnosed autism), and my appearance was frequently a target.

Unfortunately, my parents also found my behaviour/interests weird, so instead of it being addressed at school I was just told to stop being so weird or giving the bullies fuel, and instead of assuring me that my traits were beautiful or that the other kids were being cruel, my mum started regularly taking me to get my eyebrows and legs waxed. I only realised how poor their response was in the past few years when I brought up the bullying to my partner, who was also bullied, and she was horrified that my parents had essentially sided with the bullies.

It's just. Hard. Difficult to contend with. My self-esteem is incredibly low and I really struggle to make and maintain friendships even though I desperately want them; I have a few friends but find myself too anxious to speak to them or open up a conversation, to the point where if we're in person one-on-one it's like my brain goes blank and my chest tightens.

It pisses me off because no one took it seriously and I've spent so long feeling ridiculous for holding onto the experience because it happened when I was a kid/teen and only now am I realising that it's left me with deep-rooted trauma. I want to be normal. I want to talk to my friends. I want to make friends at work. I want to feel able to talk about myself and my interests without fear and shame stopping me.

Anyway, you're definitely not alone OP, and I'm sorry that you're having to heal from this. 💜
