excessive belching

This only one of my list of symptoms but this one is causing quite a lot of discomfort. It feels like air stuck in my throat and I have to force it out, that and I got that feeling of a lump in your throat thing that you get with anxiety. I don’t know why but this new semester of university has caused my symptoms to flare up or get worse. Anxiety makes me irritable. Just trying to manage this and would like some advice.
