In time, I hope you'll feel more comfortable about opening up regarding your trauma, people on the forum are usually quite supportive and I don't think most people here would invalidate you or perceive what you've been through as lesser. Especially if that event has made you contemplate ctb, I believe that's proof that what happened has had a serious effect on you and should be treated with the consideration it deserves by others.
To answer your question, yes, I've also been through what I consider major trauma but society does not view it as severely as I do. When I was a young child I believe I was molested by a doctor, and this event had a snowball effect when it came to ruining my life.
My memories are extremely hazy, but I remember the direct aftermath and feelings of being violated. My family members would hit me because I was afraid of doctors and I would be held down and forced to endure things I didn't want to. I developed an aversion (and a disgusting, weird fetish) towards medical environments when I was incredibly young. I started acting out sexually way before puberty and developed a fear of penetration. If there was a medical show on TV showing some exam or procedure my fight or flight response would kick in.
The older I got, the worse this fear and PTSD became. I would avoid anything relating to doctors like the black plague. No one understood what I was going through. By the time I was diagnosed with PTSD at age 19 it was already too late for me. I was raped by a friend of my ex boyfriend and even though I had visible injuries many people did not believe me because I refused to go to the hospital for a "rape exam."
Because of my fear, people around me would accuse me of lying or exaggerating any issues I had, as their default response for everything was to go to doctors, doctors are good trustworthy people, and I'm mentally ill and stupid. When I forced myself to go to doctors, they treated me horribly and the panic spiralled from there. In my lifetime, I can name only a handful of medical staff who actually acknowledged or believed that I have PTSD. Most people do not want to believe that medical staff can and will cause harm.
I have tried just about every drug under the sun including psychedelics and the carousel of psychiatric prescriptions. I've done years of therapy and tried to force myself to do exposure. Because I'm a woman, it's always treated as if my consent does not matter and I need to subject myself to all and any medical procedures and probing, even if my body and mind physically can't handle it. There is pretty much 0 awareness of medical PTSD.
I've been accused many times of not wanting to get better, or put in the work, but the reality is modern therapy and psychiatry is absolutely useless in a case like mine. I often feel like a 5 year old still frozen in time, unable to say no or escape. Other people rarely have compassion for me outside of this website. Hands down enduring this trauma is a major contributor in why I need to kill myself. I've now had PTSD for 20 years.
Also, I agree with you completely that dealing with problems is harder when there is no external validation and acknowledgement of them. A huge issue I've encountered throughout my life is that cases like mine are never documented or researched. 99.9% of therapists and psychiatrists have never heard of a situation like mine and end up dumbfounded. It's like being on a deserted island all alone.
