My toxic farts are destroying my partners life. I'm ashamed of myself and out of ideas, help?

So, i have IBS. Badly. Unfortunately stress and anxiety makes it worse, I get anxious about my poisonous farts and so it makes them thicker and heavier and the cycle continues.

I have tried everything, charcoal tablets, anti gas tablets, diet modifications. You name it and I've done it

Last night, i woke repeatedly to my partner blitzing the room with air freshener but complaining that my noxious farts were fighting back and winning .... I woke to him sleeping on the couch

What the fuck do I do????

My foul farts are ruining my relationship
