Relieving nausea?

[chixy]

Hey guys! I hope you're all doing ok!
I think my acid reflux is acting up. I have a lot of events and stuff coming up and i think i'm nervous about it = stressed = aciiiiiiiiid! My stomach has been a bit "worried" all day, not enough to make me suspicious but i still notice it. I've had my appetite (and have also eaten like SHIT today, like just crisps and soda! so good for the acid reflux ) so i have been eating. Towards the afternoon and up until now (1 am. My sleeping schedule is a bit weird haha) i've been feeling kind of ill, especially when i stand. I don't know if it's mostly imagination because i feel as though it gets worse when i'm actually going out somewhere, not just walking around in my house. And, like many emets, i'm more scared of v* outside of my home than in it. I don't feel like i'm actually going to v*, i think. If that's what it is than i am incredibly calm despite of it, i don't feel anxious at all, just generally annoyed and bothered by the nausea. I suspect i'm sensitive to gluten as well and i had some bread today. Anyway, i've had one of those anti acid pills (my last one) but i didn't feel like it made much difference. Do you guys have any advice on how to get some relief from all of this? I'm not sure if it's actually acid reflux because i've really not been treating my stomach well today (living on the wild side ) which means it might just be in a generally bad condition from all the unhealthy things i've been eating. I still have my appetite and i'm eating some mashed potatoes now, which made it a bit better but it's not good yet. Do you have any tips or advice??
Thank you!!!
Edit: I don't have any kind on medication that could help me like anti emetics or something. Nothing like that!
