It sounds like you started shouting at another co-worker because they started shouting at you. So maybe now you can grow from this and be aware that the next time a co-worker comes to you shouting about something that you can respond differently. Maybe say, I will talk to you about this but not if you are going to raise your voice to me. Or say, I will discuss this with you once you've calmed down. Or even just excuse YOURSELF if you need to. But know that people are going to come at you with conflict and it's all about how you respond to it that matters.

I think Tradika has a point that maybe looking for less stressful work would be a good option.
