Yeah, people treat you based on what they see and since Crohns is an internal disease it usually ends up unfair for us. It's hard and willpower alone isn't enough, that's just the beginning. Either way, my GI is going to do what it wants regardless of how I think otherwise. I've tried and ended up worse because I did push myself too hard trying to keep up and lost. Lesson learned.
I would recommend cannabis though. Pain pills (opioids and such) only increase my nausea and constipate, which is definitely not desired. We aren't allowed to take NSAID meds and Tylenol is about worthless so our options are limited. You can't OD on THC, it's natural, and solves more problems than it creates. You get high, but that can be a good or bad thing depending on your lifestyle and tolerance. Living at the end of the rope often presents options you wouldn't otherwise consider, and that being the case, cannabis is greatly beneficial - in my experience.
