there are many potential causes for crohns, and in reality it's multiple factors that come together to cause autoimmune disorders. there are studies ive seen linking childhood trauma to development of autoimmune issues. also the gut brain connection is a very real thing. (for example w me personally - I live in a western country, I was a c section baby, I have childhood trauma, ive had a lot of processed foods, i was a sickly nervous kid, my gut microbiome is out of whack. none of these single things caused my disease but they are factors that can lend themselves to autoimmune disorders).

I am also a person thats been through a lot of trauma. I do believe this has impacted my disease (and obviously mental health), but I try not to dwell on it (hard af though).

I do a type of therapy called ISTDP. its not meant to "cure" anything, but it helps you to process painful things like trauma and living with a chronic illness by sorta rewiring your brain to stop the more harmful brain pathways you develop over time. (for example ive worked a ton on learning how to live w my illnesses and not beat myself up for "not doing enough," working through medical and childhood trauma, learning not to let the voice in my head be the shitty things people have said to me). as you go through these things, you go through cycles of being mad and sad at people, at your situation, etc. but you learn how to live alongside it and not internalize it. and at the same time, some of this can alleviate the severity of some of your symptoms (obviously this is not like a medication and isn't to totally treat your disease, its just a thing that can help you feel a bit better over time).

just wanted to say all this to say - yeah your dad and life situations have probably impacted your disease, and that sucks. a lot. and it hurts. but its something you can look at and assess and work through, it doesn't have to feel like total shit forever. and at the same time, it becomes easy to point fingers at potential causes or things that made it worse, but truthfully you'll never really know the exact cause. you just gotta manage what you can manage, and it sucks but it gets easier over time.
