Trapped wind!!

I’ve had trapped wind now for 4 weeks on and off, it feels hard to push out, I’ve had watery stool for 5 days ish, before that I was constipated, my stomach gurgles all the time! I’ve had IBS for ten years, I’ve had long covid for 13 months and I’ve got extreme health anxiety which has been flaring up the last 5/6 weeks... please help I’m worrying myself mad (I have a GP appt on Tuesday)
