I have a hard time staying clean all day

I feel like I have to shower twice a day. I get smelly so easily and it’s really embarrassing. I shower first thing in the morning and practice all good hygiene everyday (washing myself, brushing my teeth, using deodorant). I sweat so easily, my breath gets gross really fast, and I just feel gross all the time. I hate it. Does anyone have any tips for me? It’s frustrating and it harms my self-confidence
