Seeking Information and Support for Hirschsprungs Disease Diagnosis

hello! i am currently pursuing a hirschsprungs diagnosis. i have had chronic constipation my entire life, i am now almost twenty and my constipation and pain only seems to be getting worse. i was wondering if anyone here has had hirschsprungs disease and if theyd be willing to message me about any information or tips or surgery outcomes? whatever theyd be comfortable with? i am kinda just grasping at straws. this is the fourth gi doctor i have seen, not counting the countless ones i saw as a baby, and i feel hopeless at this point. so any information is very appreciated, thank you!
