Welcome to the forum. I'm sure you'll get lots of support from the amazing folk here.
Childhood medical trauma. Sadly Yes.
I was born with severe hypospadias. I started reconstructive surgery age 3, stopped when I was 16, (about 30 operations because the surgery kept failing). The procedures are too numerous to recount but most were pretty awful.
Mental health issues. My psycho-sexual development was significantly affected, because the surgery was on my genitals. So repeated exposure, touching, severe pain, embarrassment, humiliation. Treatments and procedures also continued at home. I suffer from depression, anxiety, low self esteem and body dysmorphia. I repeatedly act out memories of traumatizing and humiliating procedures on my self.
In a cruel twist of fate my first son was also born with the condition (clearly genetic in my line). I made sure his treatment was a very different experience to mine.
Diagnosed with complex trauma and depression five years ago. One significant suicide attempt. There was no psychological support during the 13 years I was having surgeries as a child.
What has helped. Time with a therapist specialising in psycho-sexual problems (self funded). CBT and compassionate mind therapy from a competent therapist. Constant validation that my experiences were bad enough to cause me problems, and that I was not weak, or a failure, to be affected, and help with body dysmorphia. Work on anxiety and depression and on medication for three years (stopped 2 years ago).
So yes, I absolutely know there is such a thing as medical trauma. But recounting my experiences doesn't help you and I totally agree with
@Chava if you are struggling with issues professional help is the way to go. I ignored my issues for nearly 40 years and in the end it caught up with me.
I hope you can get some professional input, and you make use of the wealth of experience available here.
Best wishes.
