is this an IBS flare up?

Hi I've been under a lot of stress the past couple of weeks and last week I started having diarrhea every morning, nausea, excessive swallowing, bit of burning in stomach, dry mouth and lips, more wind and gas, on and off bloating, stomach feeling off and I'm also waking up early with racing heart and feeling hot I have health anxiety so I'm really worried about all this do you think I could be having an IBS flare up and that some of the symptoms could also be down to my anxiety? I don't know how to get through this I'm scared I'm always going to feel like this please if anyone has any advice or has experienced any of this please reply to me
