anxiety poop please help

Does anyone else struggle with anxiety poop?? As a kid I never used to get this but it started in high school when I got super stressed for an exam (it was a pretty important one) and all of a sudden had the really bad urge to poop. It's been 4 years since then and everytime I encounter a stressful situation I always have to poop and it's super inconvenient since sometimes I dont end up actually pooping anything. The feeling is super uncomfortable as you can probably imagine but I dont know what to do anymore. I tried fixing my diet but it didnt alleviate the symptoms and I get anxious really easily so idk what else to do.
