Armpit still stinks after washing and shaving?

I went through a period of depression and didn’t shower for days on end. Now I finally showered with warm water and exfoliated and shaved my armpits but the smell is still there and it’s driving me crazy. It’s not my diet. My hands are wrinkly from the amount of antibacterial soap and shampoo I used on my armpits. Does it mean that the soap isn’t killing the bacteria? Or is it just a smell? It’s slightly less noticeable but it’s still there and I know it’ll start smelling more when I sweat. Do I put deodorant on my irritated skin from exfoliation and shaving? Or will it make things worse? Thanks all.
