If you have continuous gas during prayer, can you purposely let it out?

I have this very embarrassing problem with gas and anxiety, and it is continuous and affecting my prayer. I am physically so exhausted and tired because every time I pray I have to hold it in. I know that if you have continuous gas, then you can pray like that, but under that ruling can one purposely let gas out during prayer sometimes just to make himself feel better, even if he's physically capable of holding it in?
