not sure what’s going on

the past couple weeks whenever i have to go somewhere in the morning, i always get nauseous. Most the time i have morning diarrhea and dry heave. i’m not pregnant and there is no possibility that i would be. i feel like i give my self anxiety unknowingly i’m the morning which caused stress poop and nausea. are there any tips on how to make it go away? i can’t take pepto or tums bc they make me even more sick
