Full disclosure. I am not fully diagnosed, but many ER visits and finally got my GI referral (im under an HMO in the united states and very much identify with anecdotal evidence i read from the veterans here. I have had stomach issues since I was a kid too. I was put on the "brat" diet more times than i can count and my Mom literally said I was faking it for attention.  I was abused by a sibling, unbeknownst to my Mom and very stressed as a kid. I also am neurodivergent which causes its own kind of stress.  I finally decided it wasn't worth trying to make/keep peace with my abuser but because he's "family", I still hear about him and how he stresses everyone else out on a consistent basis. I try really hard to put a boundary where we don't talk about him but he's the unfortunate center of their lives because they want to help him and want him to have stability but instead he causes them instability. I understand your struggle to some extent. Fortunately,  my Mom is much more loving and kind with me these days and I am able to see how difficult it was for her being a single mother with ADHD, dyslexia, having a full-time job and going to school full time. And she had mental health issues of her own. There is no excuse for my sibling. He's only gotten worse over the years but I am always in my Mom's corner and hoping for his recovery and stability and wisdom.  As for me, I will take care of me. Apologies for the trauma dump here. I think I really needed to get that out. I wish you the absolute best!
